Question

What is the rate of reaction?

Answer 1

Reaction rate, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

Answer 2

RATE OF REACTION ;-

The rate of change of concentration of any species taking part in a chemical reaction with time is known as Rate of Reaction .

for a reaction R -> P ;

• Rate =  $\frac{Change in Concentration}{Time}$ = $\frac{ΔC}{Δt}$
• Unit = $\frac{mol/l}{s} \ or \ \frac{atm}{s} (for \gaseous\ reactant \or\ product)$
