TOPIC 11 Further equilibrium 11.1 Chemical equilibrium
... If the pressure is increased then the volume of the reaction mixture will decrease. This will result in an instantaneous equal increase in the concentration of each component. However, the increase in the magnitude of [CH3OH(g)][H2(g)]2 will be greater than the increase in the magnitude of [CH3OH(g) ...
