The following thermal decomposition occurs at \(400 \mathrm{~K}\) :

\[ A(\mathrm{~s}) \rightarrow B(\mathrm{~s})+C(\mathrm{~g}) \]

The standard Gibbs free energy of the reaction, \(\Delta G^{0}=85,000-213.73 T+6.71 T \ln\) \(T-0.00028 T^{2}\). Determine the decomposition pressure at \(400 \mathrm{~K}\) and \(700 \mathrm{~K}\). Also determine the decomposition temperature at 1 bar.
