Question

the Arrhenius Equation for the rate constant ka zpe is the number of collisions per second, and p is the orientation factor For the reaction A B , z = 1012 collision per second, and p = 0.5. At a temperature T 300.0 K, how many effective collisions occur per second CASO SO,000 17. The rate constant (ka) of a reaction is 3.46 X 102/sec at 298 K. What is the rate constant (kz) at 350.0 K, if the activation energy is 50.2 KJ/mole? a) 0.346/sec. 0.502/sec 0.702/sec a) 0.918/sec. e) 0.986/sec. 18. The rate constant of a reaction is 1.0010"/sec at 300.0 K If the rate constant increases to 1.00 X 102 at 400.0 K, What is the activation energy of this reaction? (Note: Correct unit counts for 1 point).
