Given these concentrations Ao 0 M Clo 10 M Which statement

Given these concentrations [A]o = 0 M [Clo = 1.0 M Which statement is true? a) The forward reaction occurs. b) The reverse reaction occurs c) The system is at equilibrium d) None of these.

Solution

A + 2 B ----------------- C

Q= [C]/[A][B]^2                                     [A]0= 0M     [B]0 = 0M       [C]0 = 1.0M

Q= (1.0)^2/0.0 = infinity

Q= infinity

Kc= 300

Q> Kc

The reaction is favoured to the left side.i,e backword reaction is favoured.i,e reverse reaction is favoured.

The answer is B.
