STD 12 - 4. d and f- block elements — NEET STD 11 Science — Question

$X_2O_4(g) \to 2XO_2(g)$

$\Delta U = 2.1\, kcal, \Delta S = 20\, cal\,  K^{-1}$ at $300\, K$.

Hence $\Delta G$ is ....$kcal$

$(i)$ Increase in concentration of reactant increases the rate of a zero order reaction

$(ii)$ Rate constant $k$ is equal to $'A'$ if $E_a = 0$

$(iii)$ Rate constant $k$ is equal to $'A'$ if $E_a = \infty$

$(iv)$ $log_e k$  vs  $T$ is a straight line

$(v)$ $log_ek$  vs   $1/T$ is straight line
Correct statement are
