For reversible reaction, A + B hArr C + ...

For reversible reaction, `A + B hArr C + D`, the graph for rate of reaction with time is given below.
Mark the terms (p),(q) and (r )

A

(p)-rate of backward reaction ,(q)-rate of forward reaction, (r )-equilibrium,

B

(p)-rate of forward reaction, (q)-rate of backward reaction, (r )-equilibrium

C

(p)-concentration of products (q)-concentration of reactants (r )-rate of reaction

D

(p)-instantaneous rate of reaction, (q)-variation of rate, (r )-average rate of reaction

Text Solution

Verified by Experts

The correct Answer is:
B
Rate of forward reaction decreases and rate of backward reaction increases with passage of time. At equilibrium both the rates become equal.
