So, a rate law expression for the given reaction is given as r is equal to k, a to the power of x, b to the power y and c to the power of z.
00:13
So, x, y and z, they are the order of reaction with respect to particular reactant.
00:21
Now, if we find out the value for x, y and z from the given data, then if we see the data for trial 1 and 3, we see concentration of b and concentration of c, they are constant.
00:37
Concentration of b and c are constant, whereas a concentration is becoming twice, becoming twice of initial or trial 1 and the rate of reaction is becoming 4 times of initial or trial 1.
01:07
So, we know the quadric relationship is find only in case of, quadric relationship is find only in second order reaction, hence the reaction is, reaction, reaction is second order, second order with respect to concentration of a or we can say x value is equal to 2.
01:52
Now, we see that for trial 3 and 4, the concentration of a and c, they are constant, while concentration of b is becoming twice of trial 3, whereas the rate is constant in both trial 3 and 4.
02:20
So, we can say the rate is independent, independent of concentration of b or we can say the reaction is 0 order with respect to b...
