1. Remember that rate constants ( k, unit of 1/ time ) are described by the Arrhenius equation, and depend on the pre-exponential factor ( A, mainly entropic considerations), the activation energy (Ea), and the temperature (T) : k=AeEa/RT where R=8.314e3kJ/molK a: For a reaction whose A=10131/seconds and Ea=200kJ/mol, generate a plot of time (1/k, units of minutes, in y-axis) versus temperature ( T, units of K, in x-axis) for 600 to 900K. b : At what temperature is the time to observe a reaction practically zero minutes
