Well, students, so in this question we are given with this rate expression, right? and this is the constant, rate constant k value.
00:08
Okay, this k value is given and we have told that the rate depends upon the concentration of a and the concentration of b.
00:15
Right.
00:15
So this rate value is also given to us and this concentration of a is also given to us and we have to find the concentration of b.
00:23
Right.
00:23
So you can simply put on this value in our equation 1.
00:26
So from equation 1, from equation 1, we can simply put on all the values that are given.
00:38
So rate value is 0 .0669, right? this units also with that, and we have this k value or the constant value that is also given already, multiply by the concentration of a, a concentration of 0 .25 .5...
