When more than one stoichiometric equation is used to represent the observed changes i.e. Series and Parallel reaction.
The reaction which occurs in series to get final product. In series reaction we have a byproduct.
The reactions which occurs in parallel, implies simultaneously two different products are obtained from same reagent.
RATE OF REACTION:
(i) Average Rate:
The rate measured over a long time interval called average rate
- Negative sign before reaction rate signifies a decrease in concentration.
- Positive sign before reaction rate signifies an increase in concentration.
(ii) Instantaneous rate :
- The rate of change of concentration of reactant or product over a very small interval of time (rate at any particular instant)
- Instantaneous, rate is more practical rather than average rate.
The tangent at any point on the graph gives it’s the rate of the reaction.
