in options (a) to (d) is correct?
1. C (g) + 4 H (g) → CH₄ (g); ∆ᵣH = x kJ mol⁻¹
2. C (graphite) + 2H₂ (g) → CH₄ (g); ∆ᵣH = y kJ mol⁻¹
(a) x = y (b) x = 2y
(c) x > y (d) x < y

Answer 1

Answer:

Consider the reactions given below. On the basis of these

reactions find out which of the algebraic relationship given

in options (a) to (d) is correct?

1. C (g) + 4 H (g) → CH₄ (g); ∆ᵣH = x kJ mol⁻¹

2. C (graphite) + 2H₂ (g) → CH₄ (g); ∆ᵣH = y kJ mol⁻¹

(a) x = y (b) x = 2y

(c) x > y (d) x < y
