Question

Reaction coordinate diagram for the reaction
$COC{l}_2(g)⟶CO(g)+C{l}_2(g),\Delta H=103.1kJ$
with $\log k\left({\min }^{-1}\right)=\frac{-11420}{T}+15.154$ is

• A.
• B.
• C. Both (a) and (b)
• D. None o f these

Answer 1

Answer: (B)

By Arrhenius equation

${\log }_{10}k=-\frac{E_a}{2.303RT}+\log A$

$\therefore \frac{E_a}{2.303}=11420K$

$\therefore E_a=11420\times 2.303\times RK$

$=11420\times 2.303\times 8.314\times 10^{-3}kJmol{K}^{-1}K$

$=218.67kJmo{l}^{-1}$

Given reaction is endothermic, $\Delta H=+103.1kJ$

Thus, reaction-coordinate diagram is
