14. When studying the kinetics of thermal decomposition of substance A, the initial concentration of which is 100 mol/m3, the values ​​of reaction rate constants at different temperatures were obtained
T,K 840 850 860 870 880
k, min-1 0.0097 0.0159 0.0254 0.041 0.0633

Determine: 1) graphically the value of activation energy;
2) calculate the value of the pre-exponential factor;
3) calculate the concentration of the starting substance 15 minutes from the start of the reaction, which occurs at a temperature of 840 K.
