Define the terms 'order of reaction' and 'rate constant'
Perform calculations using the rate equation
Explain the qualitative effect of changes in temperature on the rate constant k
Perform calculations using the equation k = Ae–Ea/RT
Understand that the equation k = Ae–Ea/RT can be rearranged into the form ln k = –Ea /RT + ln A and know how to use this rearranged equation with experimental data to plot a straight line graph with slope –Ea/R
These equations and the gas constant, R, will be given when required.
The rate of a chemical reaction is related to the concentration of reactants by a rate equation of the form:
Rate = k[A]m [B]n
where m and n are the orders of reaction with respect to reactants A and B and k is the rate constant.
The orders m and n are restricted to the values 0, 1, and 2.
The rate constant k varies with temperature as shown by the equation:
k = Ae–Ea/RT
where A is a constant, known as the Arrhenius constant, Ea is the activation energy and T is the temperature in K.
