Rate constant

The rate constant, also known as the reaction rate constant, is a proportionality constant that relates the rate of a chemical reaction to the concentrations of the reactants. It is typically denoted by the symbol k and has units of inverse time (e.g., s^-1, min^-1, etc.). The value of the rate constant depends on a…

Enthalpy of reaction

The enthalpy of reaction (ΔHrxn) is the amount of heat released or absorbed during a chemical reaction at a constant pressure. It represents the change in the enthalpy of the system as reactants are transformed into products. If the enthalpy of reaction is negative (ΔHrxn < 0), it means that the reaction is exothermic, and…
