Which of the following statements (s) is (are) correct?

Options

A. A plot of log `K_(p)` versus `1//T` is linear
B. A plot of log [X] versus time is linear for a first order reaction `X rarr P`
C. A plot of log P versus `1//T` is linear at constant volume
D. A plot of P versus `1//V` is linear at constant temperature

Answer

B,D

Explanation

(B) For the reaction `X rarr P`
`log [X]= -k/2.303 t+log [X]_(0)`
As such a graph between `log [X]` and time t is linear.
(D) At constant temperature,
`V=K/P` (Boyle's Law)
or `P=K//V`
As such a graph between P and `1//V` is linear at constant temperature.
(Please note that a graph between `log k` and `1//T` is linear and not between `log K_(p)` and `1//T`).
