# Doubts from Thermodynamics

For 1st getting c?

answer is 2, 3... how?

On solving you get z=3 and n=5.

This is useful for option first only.

For second and third option it think there is no use of given data in question.

it should be 2 and 3 for second question.

1 and 3 for second

That is what I got for 2nd problem.

Don't know where it is wrong

It's ask for single step process and isothermal is infinitely many step process

You have solution then post it.

I was also getting -1120 but answer is -600
