Problem 1: The initial reaction rate for the elementary reaction 2A + B 4C was measured as a function of temperature when the concentration of A was 2 M and that of B was 1.5 M. -TA(mol/dm³ s): 0.002 0.046 0.72 8.33 T(K): 300 320 340 360 (a) What is the activation energy? (b) What is the frequency factor?
