Question

The following statement(s) is (are) correct :
(i) A plot of $\log K_p$ versus $1/T$ is linear
(ii) A plot of $\log [X]$ versus time is linear for a first order reaction, $X\to P$
(iii) A plot of $\log P$ versus $1/T$ is linear at constant volume
(iv) A plot of $P$ versus $1/V$ is linear at constant temperature

• A. (i) only
• B. (ii) only
• C. (i) and (iv)
• D. (i), (ii) and (iv)

Answer 1

Answer: (D)

The relevant expressions are as follows.
(i) $\log K_p=-\frac{\Delta H}{R}\frac{1}{T}+I$
(ii) $\log [X]=\log [X{]}_0+kt$
(iii) $P/T=$ constant ( $V$ constant)
(iv) $PV=$ constant $(T$ constant $)$
