Consdier a first order gas phase reaction,
A(g) `rarr` 2B(g) + C(g)
The initial pressure taking only A in a rigid vessel was found to be P atme. After a lapse of 10 minutes, the pressure of the system increases by x units and became `P_(10)` atm. The rate constant for the reaction is given by :

A

`k=(2.303)/(10)"log"(P)/(P+x)"min"^(-1)`

B

`k=(2.303)/(10)"log"(P)/(P-(x)/(2))"min"^(-1)`

C

`k=2.303xx"6 log"(P)/(P_(10)-(P))"hr"^(-1)`

D

`k=2.303xx"6 log"(2P)/(3P-P_(10))"hr"^(-1)`
