Paragraph 1 (2 TO 3)

Thermal decomposition of gaseous $\mathrm{X}_{2}$ to gaseous X at 298 K takes place according to the following equation :

The standard reaction Gibbs energy, , 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 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 $\left.: \mathrm{R}=0.083 \mathrm{L} \text { bar } \mathrm{K}^{-1} \mathrm{mol}^{-1}\right)$
