Acitivity

Followin are the serms about ac itivty and selectivity: I. Acitivity is the ability of catalysts to accelerate chemical reactions and selectivity is the ability of catalysts to direct reaction to yield particular products. II. Activity is the ability of catalyst and selectivity is the ability of catalysts to accelerate chemical reactions. Select the correct term :

Red hot carbon will remove oxygen from the oxide XO " and " YO but not from ZO . Y will remove oxygen from XO . Use this evidence to deduce the order of acitivity of the three metals X, Y and Z putting the most active frist:
