Equilibrium constants can be used to calculate the concentrations of reactants and products that will be present at equilibrium. Learning Objective. Calculate the concentrations of reaction components at equilibrium given the starting concentrations and the equilibrium constant.
Kinetics Of A Reaction - Calculating Activation Energy. The rate constant of a reaction can be expressed as. k = Ae-Ea/RT. which is called the Arrhenius equation. Taking the natural log of both sides of the Arrhenius equation gives. ln k = -Ea/R(1/T) + ln A. The equation above is of the form y = mx + b, where y = ln k, m = -Ea/RT, x = 1/T, and b = ln A. For a reaction whose rate constant obeys the Arrhenius equation, a plot of ln k vs 1/T gives a straight line and it's slope can be used to determine Ea.
