1. What are the units for each of the following if concentration
is expressed in molarity and time in hours:
i. Rate of a chemical reaction
i. Rate constant for a zero-order reaction
iii. Rate constant for a second order
reaction
Homework Answers
Ans. As Concentration expressed in Molarity ( M ) and Time expressed in hours ( hr )
i.
Unit of Rate of a chemical reaction : M hr-1
ii.
Now , Unit of Rate constant : M1-n hr-1
where n is the order of reaction
So , For a zero - order reaction , n = 0
Unit of Rate constant : M hr-1
iii.
For a second - order reaction , n = 2
So , Unit of Rate constant : M-1 hr-1

Learning Goal: To understand how to use integrated rate laws to solve for concentration. A car starts at mile marker 145 on a highway and drives at 55 mi/hr in the direction of decreasing marker numbers. What mile marker will the car reach after 2 hours? This problem can easily be solved by calculating how far the car travels and subtracting that distance from the starting marker of 145. 55 mi/hr×2 hr=110 miles traveled milemarker 145−110 miles=milemarker 35 If we...

The half-life of a reaction,
t1/2, is the time it takes for the reactant concentration [A] to
decrease by half. For example, after one half-life the
concentration falls from the initial concentration [A]0 to [A]0/2,
after a second half-life to [A]0/4, after a third half-life to
[A]0/8, and so on. on. For a first-order reaction, the half-life is
constant. It depends only on the rate constant k and not on the
reactant concentration. It is expressed as t1/2=0.693k For a...
