WebMar 24, 2024 · Heats of reaction are typically measured in kilojoules. It is important to include the physical states of the reactants and products in a thermochemical equation as the value of the ΔH depends on those states. Endothermic reactions absorb energy from the surroundings as the reaction occurs. WebReaction rates are therefore determined by measuring the time dependence of some property that can be related to reactant or product amounts. Rates of reactions that …
