An exothermic reaction is a type of reaction that dissipates heat as the reaction proceeds. This would mean that in a closed system, when a reaction proceeds and is endothermic, the temperature of the solution or the system would increase so as to maintain the equilibrium with the whole system.
<span>Higher energy = shorter wavelength Frequency is one cycle over an amount of time (seconds) So higher frequency = higher energy = shorter wavelength</span>
