Title: Shouldn't K be different?
Post by: abhistud on September 10, 2017, 11:47:43 PM

This is the question:

This is how he did it:

Then, he said that if K is equal in both the cases, then, it is first order. But, shouldn't K vary with time in first order reaction?

How are you defining first order reaction?
