Vedclass · Answer

(B) The relationship between $K_p$ and $K_c$ is given by $K_p = K_c(RT)^{\Delta n_g}$.Here,$\Delta n_g$ is the change in the number of moles of gaseous products and reactants.$\Delta n_g = (\sum n_g)_{	ext{products}} - (\sum n_g)_{	ext{reactants}}$.For the reaction $SO_2(g) + \frac{1}{2} O_2(g) ightleftharpoons SO_3(g)$:$\Delta n_g = 1 - (1 + \frac{1}{2}) = 1 - \frac{3}{2} = -\frac{1}{2}$.Comparing this with $K_p = K_c(RT)^x$,we get $x = -\frac{1}{2}$.

For the reaction $SO_2 + \frac{1}{2} O_2 \rightleftharpoons SO_3$,if we write $K_p = K_c(RT)^x$,then $x$ becomes
