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.
