The rate constant k is dependent on the concentration of the reactant the nature

Question

The rate constant k is dependent on the concentration of the reactant the nature of the reactants the temperature the order of the reaction none of these one of these two of these three of these all of these What would happen if the kinetic energy of the reactants was not enough to provide the needed activation energy? The products would be produced at a lower energy state. The rate of the reaction would tend to increase. The activated complex would convert ion to products. The reactants would continue to exist in their present form. The products would form at an unstable energy state.

Explanation / Answer

18. For first order,

k = (ln[Ao] - ln[A])/t = (ln(100) - ln(60))/48.1

B) 1.06 x 10^-2 s-1

19. The half life = ln(2)/k = 0.693/0.0107

B) 64.6 s

20. The rate constant is dependent upon,

C) Two of these

21. If kinetic energy of reactant is not sufficient,

D) The reactants would continue to exist in the present form.
