QUESTION: 1

The half life of a first order reaction is equal to:

Solution:

QUESTION: 2

For zero order reaction, linear plot was obtained for [A] vs t, the slope of the line is equal to:

Solution:

For zero order reaction the rate equation is [A] = -kt + [Ao]

Thus the slope of the line is -ko

QUESTION: 3

The first order rate constant for the decomposition of N_{2}O_{5} is 6.2 x 10^{-4} sec^{-1}. The t_{1/2} of the decomposition reaction is

Solution:

QUESTION: 4

Find the overall order of a reaction whose rate constant is k = 3x10^{-4} s^{-1}

Solution:

QUESTION: 5

Which of the following represents the expression for the 3/4^{th} life of a first order reaction?

Solution:

QUESTION: 6

The type of reaction that gives constant half life is

Solution:

QUESTION: 7

The half life period of first order reaction is 15 min. Its rate constant will be equal to

Solution:

The half life of a reaction is 15 min

So,

Here we go..

Formula to be used :

K =0.693/t = 0.693/15

__= 0.462/10 = 0.0462 min^-1

QUESTION: 8

For zero order reaction, the integrated rate equation is:

Solution:

QUESTION: 9

The half life of a zero order reaction is equal to:

Solution:

QUESTION: 10
