Question

Chemical Equilibrium Characteristics Consider the reaction: H20(g)Co(g) = H2(g) Co2(g) Which the following statements are true and which are false. In general, at a given temperature, the reaction quotient (Q) is a constant. true 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 false time 14C may be found in both CO and CO2 molecules. At equilibrium, individual molecules may be subject to rapid chemical transformations false The equilibrium position independent of the initial concentrations. true At equilibrium, the overalll composition of the reaction mixture is constant. true the two vessels 1 mol of H20(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 H2(g) false are not equivalent.

Answer 1

Chemical Equilibrium: In a chemical reaction the point at which the rate of formation of products is equal to the rate of formation of the reactants is called Equilibrium position.

In a chemical process there are two reactions going. one is the Forward reaction where the reactants form products and the other Backward Reaction where the products form the reactants.

When the rate of both Forward and backward reaction is same, equilibrium is achieved.
