Solution
The ability of the catalyst to direct a reaction to yield a particular product is referred to as the selectivity of the catalyst. For example, by using different catalysts, we can get different products for the reaction between H2 and CO.
(i) \[\ce{CO_{(g)} + 3H2_{(g)} ->[Ni] CH4_{(g)} + H2O_{(g)}}\]
(ii) \[\ce{CO_{(g)} + 2H2_{(g)} ->[Cu/ZnO][CrO3] CH3OH_{(g)}}\]
(iii) \[\ce{CO_{(g)} + H2_{(g)} ->[Cu] HCHO_{(g)}}\]
