During the industrial synthesis of methanol (CH 3 OH), carbon monoxide (CO) reacts with hydrogen gas. For methanol, H= -100.4 kJ/mol. CO(g) + 2 H2(g)

During the industrial synthesis of methanol (CH₃OH), carbon monoxide (CO) reacts with hydrogen gas. For methanol, ΔH= -100.4 kJ/mol.

CO(g) + 2 H2(g) à CH3OH(l) ΔH= -100.4 kJ/mol

2. Is it better to maintain this system at a low or high temperature, to obtain a good output?

3. Is it preferable to maintain this system at high or low pressure? Explain.
