Question

Which of the following statements are true and which are false.

In general, at a given temperature, the reaction quotient (Q) is a constant.

1 mol of H2O(g) and 1 mol of CO(g) are placed in a vessel and 1 mol of H2(g) and 1 mol of CO2(g) are placed in another of equal volume. At equilibrium, at 350°C, the amounts of H2O(g) in the two vessels are equivalent.

Amounts of all reactants and products corresponding to an exact equilibrium composition for this reaction are sealed in a vessel. The CO placed in the vessel is labelled with 14C. After an indefinite period of time 14C would still be found only in the CO molecules and not in CO2.

At equilibrium, individual molecules cannot undergo any chemical reactions.

At equilibrium, the overall composition of the reaction mixture is changing rapidly.

The equilibrium constant does not reveal the rate of that reaction.

Explanation / Answer

1. True : Reaction quatient is based on initial concentrations of products and reactants

2. Not true:Equilibrium constants are different for both reactions,so the amount of H2O will different

3.True

4.True

5.Not true: At equilibrium no net reaction , so no composition change

6.Not true: rate of forward reaction is equal to rate of backward reaction
