Consider a first order gas phase decomposition reaction given below:
` A (g) to B(g) +C(g)`
The initial pressure of the system before decomposition of A was pi. After lapse of time 'T', total pressure of the system increased by x units and became '`p_t`'. The rate constant k for the reaction is given as

A

`k= ( 2.303 )/(t) "log" ( p i)/(p I - x) `

B

`k= ( 2.303 )/(t) "log" ( 2p i)/(p I - x) `

C

`k= ( 2.303 )/(t) "log" ( p i)/(p I - p_t) `

D

`k= ( 2.303 )/(t) "log" ( p i)/(p i - x) `
