Why is the law of mass action important?
This law can be used to explain the behavior exhibited by solutions in dynamic equilibria. The law of mass action also suggests that the ratio of the reactant concentration and the product concentration is constant at a state of chemical equilibrium.
What is law of mass action in chemistry class 11?
The rate at which a substance reacts is proportional to its active mass and hence the rate of a chemical reaction is proportional to the product of the active masses of the reactants.
Who proposed the law of mass action?
What is Rate law and law of mass action?
Answer Verified. Hint: Law of mass action is a concept of masses and concentrations but rate law is a concept of chemical kinetics. Both the terms are related, the rate of a chemical reaction is directly proportional to the concentration of reactants.
What is positive catalyst give an example?
A positive catalyst, or just catalyst for short, are substances that help hasten a chemical reaction. Some typical examples include biological catalysts Amylase, Maltase, Protease, and Lipase; as well as popular chemicals like sulfuric acid and manganese dioxide
Is law of mass action applicable to physical equilibrium?
(C) physical equilibrium. (D) both homogeneous and heterogeneous chemical equilibrium. Hint: The law of mass action says that the rate at which a chemical reaction will occur depends upon the concentration of the reacting species present.
Does law of mass action apply on the following reaction?
Yes, law of mass action apply here. According to the law of mass action, mass of reactants is always equal to the mass of products. of molecules in reactants is 4 and that of products is also 4. hence, the law is applicable here
What is relationship between active mass and rate of reaction?
“The rate at which a substance reacts is directly proportional to its active mass and rate of a chemical reaction is directly proportional to product of active masses of reactants each raised to a power equal to corresponding stoichiometric coefficient appearing in the balanced chemical equation”.
What is meant by half life period?
Half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive …
What is average life period?
The average life is the length of time the principal of a debt issue is expected to be outstanding. In loans, mortgages, and bonds, the average life is the average period of time before the debt is repaid through amortization or sinking fund payments
How do you calculate a half-life?
How to calculate the half-life
- Determine the initial amount of a substance.
- Determine the final amount of a substance – for instance, N(t) = 2.1 kg .
- Measure how long it took for that amount of material to decay.
- Input these values into our half-life calculator.
What does weighted average life mean?
The weighted average life (WAL) is the average length of time that each dollar of unpaid principal on a loan, a mortgage, or an amortizing bond remains outstanding
How do you know how long you will live?
- Age & Gender. How long you have already lived is one of the best predictors of how long you may live.
- Height & Weight. Weight problems and obesity are epidemics in the USA in both kids and adults.
- Family History. Like gender and age, you can’t control family history.
- Blood Pressure.
Can I live to be 100?
These days, while statistical life expectancy in the U.S. is about 80 years, living well into one’s 80s or 90s is a perfectly realistic expectation for many. Even centenarians — people who are 100 years old or more — are on the rise. In 2015, some 72,000 Americans were centenarians
What foods make you live longer?
A heart-healthy diet is one that includes:
- Fruits and vegetables.
- Whole grains.
- Low-fat dairy products like yogurt and cheese.
- Skinless poultry.
- Lots of fish.
- Nuts and beans.
- Non-tropical vegetable oils (olive, corn, peanut, and safflower oils)
What happens to your body when u stop eating meat?
Energy Loss. You may feel tired and weak if you cut meat out of your diet. That’s because you’re missing an important source of protein and iron, both of which give you energy. The body absorbs more iron from meat than other foods, but it’s not your only choice
How bad is meat for your health?
In general, red meats (beef, pork and lamb) have more saturated (bad) fat than chicken, fish and vegetable proteins such as beans. Saturated and trans fats can raise your blood cholesterol and make heart disease worse. The unsaturated fats in fish, such as salmon, actually have health benefits
Is eating chicken everyday healthy?
Eating chicken every day is not bad, but you need to be cautious while choosing the right one and cooking it right too. Chicken may cause food poisoning because of salmonella, a bacterium found in poultry chicken that can cause food-borne illnesses. So, exercise caution!2020年9月28日
Is meat bad for your kidneys?
6. Eating Too Much Meat. Animal protein generates high amounts of acid in the blood that can be harmful to the kidneys and cause acidosis – a condition in which kidneys cannot eliminate acid fast enough.
