Indicate the order of reaction consistent with each observation.
a. The half-life of the reaction gets shorter as the initial concentration is incr eased.
b. A plot of the natural Jog of the concentration of the reactant versus time yields a straight line.
c. The half-life of the reaction gets longer as the initial concentration is in creased.

a. Second order

b. First order

c. zero order

Explanation:

a. For a second order reaction,

As half life is inversely proportional to initial concentration, therefore, increase in intital concentration will decrease half life of the reaction.

b. First order reaction,

for first order reaction:

y = C + mx

Therefore, plot between ln A and  t is a straight line.

c. For a zero order reaction,

Half life is proportional to initial concentration, therefore, increase in initial concentration will increase half life of the reaction.

thats how its supposed to be
