Thermal decomposition of gaseous $X_2$ to gaseous X at 298 K takes place according to the following equation:

$X_2\left(g\right)\rightleftharpoons 2X\left(g\right)$

The standard reaction Gibbs energy, ${\Delta }_r{G}^0,$ of this reaction is positive. At the start of the reaction, there is one mole of $X_2$ and no X. As the reaction proceeds, the number of moles of X formed is given by $\beta$. Thus, ${\beta }_{equilibrium}$ is the number of moles of X formed at equilibrium. The reaction is carried out at a constant total pressure of 2 bar. Consider the gases to behave ideally. (Given: R = 0.083 L bar $K^{-1}mo{l}^{-1}$)



The equilibrium constant $K_p$ for this reaction at 298 K, in terms of ${\beta }_{equilibrium},$ is:
