Explanation / Answer

2. In many reactions involving gases and liquids, the rate of reaction is increased by increasing the rate of reaction. It doesnt mean doubling the concentration will double the rate of reaction that actually depends upon the order of reaction.

In some cases it doesnot change. For example the cases in which the process is divided in small steps.

And some other step defines the rate.

5. b is the answer. Standard procedure is to omit solid because they have constant concentration.

Please post question seperately.
