$($a$)$ Estimate the standard heat of reaction $(H_{298}^0),$ and the equilibrium constant $K_a$ at $750K$

for the reaction $CO(g)+2H_2(g)harrC{H}_{3}OH(g).$ Assume standard heat of reaction to be

independent of temperature to be constant. Latent heat of vaporization and saturation pressure

of $C{H}_{3}OH$ at $298\mathrm{.}15K$ is $38\mathrm{.}83k\frac{J}{m}ol$ and $16\mathrm{.}8$kPa respectively.

$($b$)$ Estimate the mole fraction of carbon monoxide in the gas phase at equilibrium $(T=750$

$K,P=2$ bar$)$ if an equimolar mixture of $CO$ and $H_2$ was fed to the reactor.
