Shouldn't K be different?
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?

What is k?
It is the rate constant and it can be changed only changing the temperature for a given reaction.
If reaction is carried out at the same temperature then value of k is constant.
