Question

What does it mean to describe a reaction as "reversible"? When writing an equation, how is a reversible reaction distinguished from a nonreversible reaction? If a reaction is reversible, when can it be said to have reached equilibrium? Benzene is one of the compounds used as octane enhancers in unleaded gasoline. It is manufactured by the catalytic conversion of acetylene to benzene: 3C_2H_2(g) rightarrow C_6H_6(g). Which value of K_c would make this reaction most useful commercially? K_c almostrqualto 0.01. K_c almostequalto 1. or K_c almostequalto 10. Explain your answer. Write the mathematical expression for the equilibrium constant, K_c, for each of the following reactions: CH_4(g) + Cl_2(g) CH_3Cl(g) + HCl(g) N_2(g) + O_2(g) 2NO(g) 2SO_2(g) + O_2(g) 2SO_3(g) BaSO_3(s) BaO(s) + SO_2(g)

Explanation / Answer

Problem 1 : If reactants combine to form products and products formed recombine to give back reactant then this type of reaction is called reversible reaction.
