Question

Methanol, CH3OH, can be produced industrially by reacting CO with H2.
CO(g) + 2H2(g) ⇌ CH3OH(g) ∆ H = –91 kJ mol–1
The process can be carried out at 4 × 103 kPa and 1150K.
Which statements about this reaction are correct?
1 Increasing the temperature will increase the rate of reaction because more effective collisions will occur.
2 Lowering the temperature will reduce the rate of reaction because the forward reaction is exothermic.
3 Increasing the pressure will reduce the rate of reaction because there are a larger number of moles on the left-hand side of the equation.
