Question

Which of the following statements is/are correct? 1) The term e-Ea/RT in the Arrhenius equation is the fraction of reactant molecules having energy less than the activation energy Ea. 2) As a general rule, the probability of correctly oriented collisions between reactant molecules will be low if the molecules are structurally simple, and high if the molecules are complex. 3) The concentration dependence of the rate for an elementary process in a reaction cannot be determined from the stoichiometric coefficients for that step. O A. none O B. 2 only O C. 2 & 3 only O D. 3 only O E. 1 only

Answer 1

all three statement are wrong.

option A none is right.

1). e-Ea/RT  is the fraction of molecule having energy more than activation enrgy.

2). the probability of correctly oriented collision in complex molecule is less than simple molecule.

3). For elementry reaction (reaction having single step) concentration dependence of rate can be determined by stoichiometric coefficients.
