Test Preparation on Chemistry Test Preparations On Chemical kinetics Part 1

1.

In a reaction, A + B → Product, the rate is doubled when the concentration of B is doubled, and the rate increases by a factor of 8 when the concentrations of both the reactants (A and B) are doubled, rate law for the reaction can be written as

1
Rate = k[A] [B]
2
Rate = k[A]²[B]
3
Rate = k[A][B]²
4
Rate = k[A]²[B]²

2.

In a zero-order reaction for every 10Adeg rise of temperature, the rate is doubled. If the temperature is increased from 10AdegC to 100AdegC, the rate of the reaction will become

164 times
2128 times
3256 times
4512 times

3.

The activation energy of a reaction at a given temperature is found to be 2.303 RT J mol^-1. The ratio of rate constant to the Arrhenius factor is"

10.1
20.01
30.001
40.02

4.
