| 1. | Increase the forward reaction rate. | 
| 2. | Shift the equilibrium to favor the products. | 
| 3. | Alter the reaction pathway. | 
| 4. | Increase the speed at which equilibrium will be achieved. | 
| (i) | A catalyst lowers the activation energy of a reaction. | 
| (ii) | A catalyst allows the same rate of reaction to be achieved at a lower temperature. | 
| (iii) | A catalyst mixes with the reactants and increases the overall concentration of reactants in the rate equation. | 
Consider the following graph

Choose the incorrect statement(s)
1. Reaction is exothermic forward direction i.e., H = -ve
2. Activation energy for forward reaction is x - y
3. Using catalyst energy will decrease H value of the reaction
4. All of these
