Product description
- When studying the kinetics of thermal decomposition of substance A, the initial concentration of which is 90 mol/m3, the values of the reaction rate constants at different temperatures were obtained
T, K 835 840 845 850 855
k, min-1 0.0036 0.0050 0.0067 0.0088 0.0114
Determine: 1) the activation energy using a graphical method;
- calculate the value of the pre-exponential factor;
- calculate the concentration of the initial substance 15 minutes after the start of the reaction, which occurs at a temperature of 840 K.
