1 points   

QUESTION 4

1. A rate law can be obtained:

QUESTION 5

1. The order of a reaction is determined by:

   		adding up the coefficients from the balanced equation
   		adding up the exponents in the rate law
   		dividing the rise by the run
   		All of the above.
   		Both a and b

Answer 1

Question-1

Rate depends upon concentration, pressure,temper tempe

So all of the above is correct.

Question-2

Rate constant only depends only on temperature.(b) is correct.

Question-3

By doubling the concentration rate of quadruple the rate of reaction.

Question-4

Rate law can be obtained by graphing M v/s time

Question-5

The order of reaction is determined by adding up the exponents in the rate law
