Question
Consider the reaction: H2O(g) + CO(g) = H2(g) + CO2(g) Which of the following statements are true and which are false.
In general, at a given temperature, the reaction quotient (Q) is a constant.
The equilibrium constant is independent of the initial concentrations.
At equilibrium, individual molecules cannot undergo any chemical reactions.
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 CO2(g) in the two vessels are not 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 may be found in both CO and CO2 molecules.
At equilibrium, the overall composition of the reaction mixture is changing slowly.
Ive tried:

and many other options but the above answers i feel like were the closest i've gotten
Explanation / Answer
1) In general, at a given temperature, the reaction quotient (Q) is a constant. (true)
2) The equilibrium constant is independent of the initial concentrations.(true)
3) At equilibrium, individual molecules cannot undergo any chemical reactions. (false)
4)
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 CO2(g) in the two vessels are not equivalent.(true)
5) 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 may be found in both CO and CO2 molecules. (true)
6) At equilibrium, the overall composition of the reaction mixture is changing slowly (false)
