For the reaction${\text{SO}}_2\left(\text{g}\right)+\frac{1}{2}{\text{O}}_2\left(\text{g}\right)\rightleftharpoons {\text{SO}}_3\left(\text{g}\right)$, if${\text{K}}_{\text{P}}={\text{K}}_{\text{C}}{\left(\text{RT}\right)}^x$where the symbols have usual meaning then the value of$x$is:
(assuming ideality)
