Question

how can you distinguish 1st order and 2nd order reaction in terms of half life period of the reactiin​

Answer 1

Graphical Relations and Half Lives

1. For a zero order reaction (Half life decreases with decreasing concentration.)
2. For a 1st order reaction (Half life is constant.)
3. For a second order reaction (Half life increases with decreasing concentration.)
