Question

For the given reactions, A -> D; ∆H = x . steps involved are
A-> B , ΔΗ1 = X1
Β ->C ΔΗ2 = ?
C->D; ΔH3=x3
(1) ΔΗ2 = x -(x1+x3 )
(2) ΔΗ2 = x + X1 + X3
3) ΔΗ2 = X1 - X3- X
4) ΔΗ2 = (x1 + x) - Χ3​

Answer 1

hope u will get my point

its just the simple addition subtraction rules u need to know before solving this question.
