2. The investigation of the reaction represented by the equation: X (g) + Y (g) → Z (g), allowed to establish that the reactive cross-section in this reaction at 25.0 °C was 7.50 x 10-21 m². This was possible when comparing the experimental Arrhenius factor with the one predicted using collision theory. It is also known that the collision cross- sections of X and Y, estimated from their transport properties, are 0.95 nm² and 0.65 nm², respectively. a) If the masses are 15.5 amu and 21.7 amu for X and Y, respectively, and the rate constant is 5.25 mM-1 s-1, determine the activation energy of this reaction. b) If the steric factor in this reaction is assumed to be 1, by how much would the reaction rate increase?
