Acertain amount of gas is trapped in a nonrigid container at atmospheric pressure. if the container is cooled and the gas in the container
remains at atmospheric pressure, what will happen?
o a.
the number of moles of gas will decrease.
ob. the number of moles of gas will increase.
oc. the temperature of the gas will increase.
od.
the volume of the container will decrease.
o e.
the volume of the container will increase.

Explanation:

Given that the gas is trapped,so the gas cant escape.

The number of moles of gas inside the container will remain constant.

The initial and final pressures are the same.

So,pressure can be taken as constant.

Charles law states that at constant temperature,volume of a system is directly proportional to the temperature of the system.

Since the temperature is lowered,volume also decreases.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
