Consider the following reactions at some temperature: 2NOCI(g) � 2NO(g) + Cl2 (g) K = 1.6 X 10-5 2NO(g) � N2 (g) + 02 (g) K = 1 X 1031 For each reaction, assume some quantities of the reactants were placed in separate containers and allowed to come to equilibrium. Describe the relative amounts of reactants and products that would be present at equilibrium. At equilibrium, which is faster, the forward or reverse reaction in each case?
Homework Answers
A)As Kc is very smaller so amount of reactants are more in relative to products.
As reverse reaction is faster.
2) As Kc is very high, so amount of products are more in relative to reactants.
Forward reaction is faster
