`2A(g)rarr2B(g)+3C(g)` is a first order reaction . When the reaction started , the pressure of the system was `P_(0)` , and it was found to be `P_(t)` after time t . The rate constant of the reaction can be expressed by the equation -

Options

A. `k=(2.303)/(k)log.(3P^(0))/(P_(t))`
B. `k=(2.303)/(k)log.(3P^(0))/(3P^(0)-2P_(t))`
C. `k=(2.303)/(k)log.(3P^(0))/(5P^(0)-2P_(t))`
D. `k=(2.303)/(k)log.(P^(0))/(5P^(0)-P_(t))`

Answer

C
