1 In which of these equilibria is the forward reaction favoured by an increase in pressure? A 2HI(g) H2(g) + I2(g)
B N2O4(g) 2NO2(g)
C 2NO(g) + O2(g) 2NO2(g)
D PCl 5(g) PCl 3(g) + Cl 2(g)
2 Methanol is made in industry by a reaction between carbon monoxide and hydrogen.
CO(g) + 2H2(g) CH3OH(g) ∆H = –90 kJ / mol
The process is usually carried out at a temperature of 400°C.
Which row correctly shows the effect on both the position of the equilibrium and on the rate of the
reaction of increasing the temperature to above 400°C?
