Question

Chemical Equilibrium Characteristics

Consider the reaction:

H2O(g) + CO(g) $=$ H2(g) + CO2(g)

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

true false  At equilibrium, the overall composition of the reaction mixture is not changing.

true false  At equilibrium, individual molecules may be subject to rapid chemical transformations.

true false  The rate at which equilibrium is established can be inferred from the magnitude of the equilibrium constant.

true false  When Q < K the system will spontaneously shift to the right.

true false  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 not equivalent.

true false  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.

Answer 1

j True At equilibrium composition of mixture is constant. i) false At equilibrium , no molecule can be subjected to rapped chemical transformation 111) True. equilibirum constant is ratio of Forword reaction and backword reachon: iv) Oct True. If olk It meant [Product att (Product Cateqm [ Reactant) att (Reactant at eos so reaction go forward, means right v) False H₂O (9) & CO(g) and Hq (g) & CO₂(g) both are different species so arenown to out that we can't relate two each other vi True. yes, corbon monooxide (co) convert into co & co2 in presence of oxigen.
