Question
NO(g) + NO3(g) 2 NO2(g) rate kINO]INO3l 50. The reaction represented above occurs in a single step that involves the collision between a particle of NO and a particle of NO3. A scientist correctly calculates the rate of collisions between NO and NO that have sufficient energy to overcome the activation energy. The observed reaction rate is only a small fraction of the calculated collision rate. Which of the following best explains the discrepancy? (A) The energy of collisions between two reactant particles is frequently absorbed by collision with a third particle. particular orientation in order to react. dependent on the concentrations of the (B) The two reactant particles must collide with a (C) The activation energy for a reaction is reactant particles (D) The activation energy for a reaction is dependent on the temperature.Explanation / Answer
50. (B) The two reactant particles must collide with a particular orientation in order to react.
Steric factor decides the rate of the reaction. Steric factor is the ratio of the collisions leading to products and the total collisions. Besides having the required activation energy the reactants should have correct orientation for reaction to take place. Steric factor governs this particular aspect of the reaction rate.
