Catalyst alters the position of equilibrium.
Option: 2
Catalyst does not initiate any reaction.
Option: 3

None of the above.
Answers (1)
General characteristics of catalyst:
1. Catalyst does not initiate any reaction. It only increases the rate of the reaction.
2. Only a small amount of catalyst is required to catalyse a large number of reactants.
3. A catalyst does not alter the position of equilibrium. It only reduces the time taken to reach the equilibrium.
4. It does not alter the Gibbs energy , of a reaction. Thus, only spontaneous reaction is catalysed and not the non-spontaneous ones.
