Question

. By Hess's Law one can calculate the AH by _
(a)
Direct method
(b) Indirect method
(c)
Differentiate method (d) None of above​

Answer 1

(b) Indirect method

bcoz Acc to Hess law, ∆H through any path is same (it's bcoz ∆H is a state fxn)

So, you may go indirectly but will find the same result....

Directly toh sabb jaante hain ki aa hi jaaega ans..

So, most appropriate options seems to be (b)
