For a gaseous reaction, the rate is expressed in terms of d P d t in place of d C d t or d n d t , where C is concentration, n is number of moles and ′ P ′ is pressure of reactant. The three are related as -

Options

  1. Ad P d t = R T V d n d t = d C d t
  2. B1 R T d P d t = 1 V d n d t = d C d t
  3. Cd P d t = d n d t = d C d t
  4. DNone of these

Correct answer

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

Step-by-step solution

R a t e = d C d t C = n V and C = P R T d C d t = d d t n V = 1 V × d n d t d d t P R T = 1 R T × d P d t
