DESCRIPTION
Solving a chemistry problem
2. Based on the values of the reaction rate constants (k1 and k2) at two temperatures (T1 and T2), calculate:
a) activation energy – Еa,
b) rate constant at temperature T3 - kT3;
c) temperature coefficient of the reaction rate - γ,
d) the amount of substance consumed during time τ at temperature T3 in a volume of the reaction mixture of 1 liter, if the initial concentrations of the reacting substances are the same and equal to Co - ν.
The order of the reaction is set according to the dimension of the rate constant.
