Explain rate of reaction with its mathematical forms.

1.	Explain rate of reaction with its mathematical forms.
Answer» Solution :Rate (Velocity) of reaction : It is the ratio of change in concentration to UNIT interval of time. Mathematically, let US consider a general reaction, A(reactant) `to` B(product). Now, rate (velocity) of reaction = `+-(d[A])/(dt)=(+d[B])/(dt)=(+dc)/(dt)` where, dc = change in concentration, dt = change in time. -Ve SIGN = forward reaction where concentration of the reactant decreases. +ve sign = BACKWARD reaction where concentration of the reactant increases. [A] = concentration of reaction A [B] = concentration of product B.
