What will be the order of reaction for a chemical change having log t_((1)/(2)) vs log a? ( where a = initial concentration of rectant, t_((1)/(2)) =half life)

The rate constant of a reaction with nth order will have units:

For the hydrolysis of methyl acetate in aqueous solution, the following results were obtained : (a) Show that it follows pseudo first order reaction, as the concentration of water remains constant. (b) Calculate the average rate of reaction between the time interval 10 to 20 seconds. (Given : log 2 = 0.3010, log 4 = 0.6021)

The unit of rate constant of zero order and first order chemical reactions are respectively :

(a) For a reaction A+BrarrP, the rate is given by Rate =K[A][B]^(2) (i) How is the rate of reaction affected if the concentration of B is doubled ? (ii) What is the overall order of reaction if A is present in large excess ? (b) A first order reaction takes 30 minutes for 50% completion.
