Excess of sodium hydroxide pellets are added to dilute hydrochloric acid and the temperature change of the mixture was measured over a period of time. The given graph shows the temperature change Time (s) with time.
What can be inferred from the graph?

A

Bonds are broken only during XY, so the temperature rises.

B

Bonds are formed only during YZ, so the temperature drops.

C

The reaction is exothermic as the temperature increases from X to Y.

D

Both A and B.
