Explanation / Answer

1)

most of the time concentration of a reaction decreases but it may increase when reaction is a. reversible reaction

So best way to define is

Change in concentration of the reactant over a period of time

2)

to define rate , stoichiometric of reactant and product must be considered

Answer: True

3)

order of reaction = sum of all the powers

= power of A + power of B

= 2 + 1

= 3

Answer: 3
