Question

define instantaneous rate of reaction. explain pseudo first order reaction with suitable examples ​

Answer 1

Answer:

Instantaneous rate

The rate any particular time is called instantaneous rate where time period is 0 and in this case slope of line is called channge in concentration is called rate of chemical reaction

pseudo first order reaction

pseudo means fake mean not first order reaction

Answer 2

1)The instantaneous rxn is the rate of change of concentration of reactants and product s in a very small time interval hence the change is negligible

2)in pseudo first order reactions the actual rxn is second order but it behaves as a first order rxn as out of the two reactants one is in excess

CH3I +H2O(excess)-----CH3OH +H+ +I-

I hope this helps
