Consider a first order gas phase decomposition reaction given below :
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 ‘pt'. The rate constant k for the reaction is given as _________.
The answer is the option (ii)
A(g) | B(g) | C(g) | |
Initial Pressure: | Pi | 0 | 0 |
Pressure after time (t): | (Pi - x) | x | x |
