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

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
