Which of the following is true for the equilibrium constant of a reaction?
a. it is a ratio of the concentrations in a reaction.
b. it remains the same at different temperatures.
c. it is represented by the symbol h.
d. its value is always close to 1.

The correct answer is Option A.

Explanation:

Equilibrium constant is defined as the ratio of concentration of product to the concentration of reactants each raised to the power their stoichiometric ratios. It is represented by the symbol 'K'. For the general equilibrium equation:

The expression for equilibrium constant is given as:

There are three cases:

When K > 1; the reaction is product favored.When K = 1; the reaction is at equilibrium.When K < 1; the reaction is reactants favored.

Thus, the correct answer is Option A.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
