Q13 / 54 · JEE Advanced 2016 (Paper 1) · Chemistry
According to the Arrhenius equation,
- AA high activation energy usually implies a fast reaction
- Correct answerBRate constant increase with increase in temperature. This is due to a greater number of collisions whose energy exceeds the activation energy
- Correct answerCHigher the magnitude of activation energy, stronger is the temperature dependence of the rate constant
- Correct answerDThe pre-exponential factor is a measure of the rate at which collisions occur, irrespective of their energy.
Solution
A]
High means less k, hence slower rate.
B] = fraction of molecules having kinetic energy greater than activation energy which increase as temperature increases.
C] ln i.e., ln
D] Rate of reaction Total number of collisions × Fraction of collisions which can form product
