Consider the reactions given below.
Question:

Consider the reactions given below. On the basis of these reactions find out

which of the algebraic relations given in options (i) to (iv) is correct?

(a) C (g) + 4 H (g) → CH4 (g); ∆rH = x kJ mol–1

(b) C (graphite,s) + 2H2 (g) → CH4 (g); ∆rH = y kJ mol–1

(i) x = y

(ii) x = 2y

(iii) x > y

(iv) x < y

Solution:

Option (iii x > y is the answer.
