Q5Multiple choice
Consider a first order gas phase decomposition reaction given below : A(g) → 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 ‘pt ’ The rate constant k for the reaction is given as _________. 2.303 pi
- (i)k= log t pi − x 2.303 pi
- (ii)k= log t 2 pi − pt 2.303 pi
- (iii)k= log t 2 pi + pt 2.303 pi
- (iv)k= log t pi + x
Show answer
(ii) k= log t 2 pi − pt 2.303 pi
