For a gaseous reaction, the rate of reaction is expressed in terms of d P d t instead of d C d t or d n d t , where C is concentration and n is the number of moles. Hence, the relation between expressions is

Options

  1. Ad C d t = d n d t = V R T d P d t
  2. Bd C d t = 1 V d n d t = 1 R T d P d t
  3. Cd P d t = d n d t = d C d t
  4. Dnone of these

Correct answer

B. d C d t = 1 V d n d t = 1 R T d P d t

Step-by-step solution

P V = n R T P = n V R T = C R T 1 R T d P d t = 1 V d n d t = d C d t
