Why instantaneous rate is preferred over average rate?

Explanation

**Step-by-Step Solution:**

1. **Understanding Reaction Rates**: In chemical reactions, the rate at which reactants are converted into products can be measured. This rate can be described as either an average rate over a time interval or an instantaneous rate at a specific moment.

2. **Definition of Average Rate**: The average rate of a reaction is calculated by taking the change in concentration of reactants or products over a specific time interval. It gives a general idea of how fast the reaction occurs over that period.

3. **Definition of Instantaneous Rate**: The instantaneous rate, on the other hand, refers to the rate of reaction at a particular moment in time. It can be determined by measuring the slope of the concentration vs. time graph at a specific point.
