Question #316f1

Answer 1

The rate at which the reactants are converted into the products is called rate of reaction (or)
Decrease in concentration of reactants with respect to time is termed as rate of reaction.

`rate= (dC)/dt`. where

`C` - concentration of reactants.

Rate of reaction is measured to check at what speed a reaction is taking place and in a specified time how much yield can be obtained from the particular reactants.

Velocity:
Change in speed with respect to time is termed as Velocity.

`V=(dS)/t`, where

`S` - speed of any thing.

Velocity is a vector quantity and at a constant speed it will be zero. There are different types of velocities which can be specified from its general definition:

1. Average Velocity
2. Instantaneous Velocity
3. Constant Velocity

and many more.
