Why does the temperature of the surroundings rise during an exothermic reaction?
A
Calculate temperature change using ΔT=Tfinal−Tstarting\boxed{\Delta T = T_{\text{final}} - T_{\text{starting}}}ΔT=Tfinal−Tstarting.
B
On a reaction profile, the vertical axis shows energy and the horizontal axis shows progress of reaction.
C
Energy is transferred from the reacting chemicals to the surroundings.
D
It is endothermic, so energy must continually be supplied.
