Homework Answers
- Catalysts increases the rate of reaction. And it increases rate of reaction in both forward and backward direction.
- As catalyst increases rate of reaction from both side so equilibrium doesn't shifts anywhere.
- Catalyst decreases the activation Energy of reaction which leads in faster the rate.
Hence, Option 1 is the correct answer.
