Power is the rate of energy transfer from one form of energy to another or from one object to another. It is also the rate of work done. Therefore it can defined using the equation: P = \dfrac{\Delta W}{\Delta t} P is the power in watts \left(\text{W}\right). \Delta W is the work done in joules \left(\text{J}\right).
The rate of a reaction shows how fast reactants are converted into products. It depends on the concentrations of the reactants and the rate constant. The rate of reaction is given by the rate equation: A + B → C + D Rate = k[A]m[B]n. The constants m and n show the order of the reaction with respect to that species.
