The half-life is the time required fo

In Zero-Order Reactions

The linear expression in log C = log C
o
– Kt / 2.303 , If a straight line is obtained, it indicates that the reaction is A . zero order reaction B . second order reaction C . third order reaction D . first order reaction

For calculation of half life of reaction follows first order;

The unit of first order rate constant is:

celabl Suspensions are considered

When two reactants in the reaction have different initial concentration the difference is big the reaction is

When the temperature increase the rate of reaction will

The half - life of second order reaction is equals l

The Arrhenius equation for effect of temperature on the hydrolysis of a drug in aqueous solution :

The stability of drug affected by the following except :

The activation energy in a chemical reaction is defined as

Which of the following plots will yield a straight line for a first order ? reaction where the slope = -k

When the rate of the reaction is equal to the rate constant , the order of the reaction is

In the rate equation , when the concentration of reactants is unity then the rate is equal to

Rate constant in case of first order reaction is
