<span>At the atomic scale, the kinetic energy of atoms and molecules is sometimes referred to as heat energy. Kinetic energy is also related to the concept of temperature. Temperature is defined as the measure of the average speed of atoms and molecules. The higher the temperature, the faster these particles of matter move.</span>
Answer:
<u>Effect of adding heat to the reactions</u>
1. Shift the Reaction <em><u>backward</u></em> in First graph.
2.Shift the Reaction <em><u>forward</u></em> in second graph.
<u>Other ways to change the rate of a chemical reaction are :</u>
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.
