When initial concentration of a reactant is doubled in a reaction, its half-life period is not affected. The order of the reaction is:
Second
More than zero but less than first
Zero
First
As learnt
First Order Reaction -
The rate of the reaction is proportional to the first power of the concentration of the reaction
- wherein
Formula:
