Chemical Kinetics and Nuclear Chemistry question

2016 · Shift 1 · Q2

JEE AdvancedChemistryChemical Kinetics and Nuclear ChemistryMultiple correct+4 / −2
According to the Arrhenius equation,
  1. A
    a high activation energy usually implies a fast reaction
  2. B
    rate constant increases with increase in temperature. This is due to a greater number of collisions whose energy exceeds the activation energy
  3. C
    higher the magnitude of activation energy, stronger is the temperature dependence of the rate constant.
  4. D
    the pre-exponential factor is a measure of the rate at which collisions occur, irrespective of their energy.
