Question

For the equlibrium A->2B+Heat, the number of 'A' molecules increases if a.volume is increased b.temperature is increased c.catalyst is added d.concentration is added d.concentration of B is decreased

Answer 1

Answer:

Hey mate....

Here is your answer....

The number of A molecules will increase if the temperature is increased.

This is because the forward reaction is exothermic and therefore at elevated/increased temeratures, backward reaction is favoured according to Le chatelier principle.

Therefore the answer is option b.

Answer 2

Let us see : For the equlibrium A->2B+Heat , when  the number of 'A' molecules increases

Explanation:

Equilibrium

It is a state when rate of forward reaction becomes equal to rate of backward reaction .

In the given reaction

A ----> 2B + Heat

Th A molecules will increase when (b) temperature is increased

The reason being it is seen from the equation that it is a exothermic reaction .

Therefore, when temperature is increased the equilibrium will favour the backward reaction in accordance with Le chatlier's principle  .

Le chatlier's law ": Which states that whenever a reaction is subjected to a kind of stress then the reaction will shift in a direction in which the stress gets reduced .
