Paragraph
Thermal decomposition of gaseous X2 to gaseous X at 298 K takes place according to the following equations:
X2 (g) $$\leftrightharpoons$$ 2X (g)
The standard reaction Gibbs energy, $$\Delta _rG^o$$, of this reaction is positive. At the start of the reaction, there is one mole of X2 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 mol-1)
Question
The equilibrium constant Kp for this reaction at 298 K, in terms of $$\beta _{equilibrium}$$, is
A
$${{8\beta _{equilibrium}^2} \over {2 - {\beta _{equilibrium}}}}$$
B
$${{8\beta _{equilibrium}^2} \over {4 - {\beta _{equilibrium}^2}}}$$
C
$${{4\beta _{equilibrium}^2} \over {2 - {\beta _{equilibrium}}}}$$
D
$${{4\beta _{equilibrium}^2} \over {4 - {\beta _{equilibrium}^2}}}$$
