Question

- Explain how adding heat to the reactions shown in the diagram wuuu

Answer 1

Answer:

Effect of adding heat to the reactions

1. Shift the Reaction backward in First graph.

2.Shift the Reaction forward in second graph.

Other ways to  change the rate of a chemical reaction are :

1. Addition of Catalyst

2.Increase in surface area

3. Increase in concentration of reactant.

Explanation:

Graph 1

It shows that the reaction is exothermic in which heat is released.

According to Le-Chatelier's rule : If temperature is increased

(heat is added) in an exothermic reaction , it will shift in backward direction.

Graph 2.

It shows that the reaction is endothermic in which heat is absorbed (taken)

According to Le-Chatelier's rule : If temperature is increased

(heat is added) in an endothermic reaction , it will shift in forward direction.
