sir plz explain the following a)show that the time required for 99% of completion of a first order reaction is twice the time required for the completion of 90% b)what is the difference between molecularity and order of the reaction? c)the rate of the reaction quadruples when the temperature changes from 293K to 313K.calculate the energy of activation of a reaction assuming that it does not change with temperature.

t1 = 2.303/k log 100/100-99
t2 = 2.303 /k log 100/100-90
by solving t1=2t2
