Question:
What will be the value of
(Given :
A) 3.6
B) 0.36
C)
D)
Answer:
Solution:
$\begin{aligned} & \mathrm{CO}2(\mathrm{~g})+\mathrm{C}(\mathrm{s}) \rightleftharpoons 2 \mathrm{CO}(\mathrm{g}) \ & \Delta \mathrm{n}{\mathrm{g}}=2-1=1 \ & \mathrm{~K}{\mathrm{p}}=\mathrm{K}{\mathrm{c}}(\mathrm{RT})^{\Delta \mathrm{n}{\mathrm{g}}} \ & \mathrm{K}{\mathrm{p}}=\mathrm{K}{\mathrm{c}}(\mathrm{RT}) \ & {\left[\because \mathrm{K}{\mathrm{p}}=3\right]} \ & \mathrm{K}{\mathrm{c}}=\frac{\mathrm{K}{\mathrm{p}}}{\mathrm{RT}}=\frac{3}{0.083 \times 1000} \ & =0.036 \ & =3.6 \times 10^{-2}\end{aligned}$
