Question

Three thermochemical equations are given below:
(i) C(graphite) + O₂(g) → CO₂(g); ∆ᵣH° = x kJ mol⁻¹
(ii) C(graphite) + 1/2O₂(g) → CO(g); ∆ᵣH° = y kJ mol⁻¹
(iii) CO(g) + 1/2 O₂(g) → CO₂(g); ∆ᵣH° = z kJ mol⁻¹
Based on the above equations, find out which of the
relationship given below is correct? [NEET Kar. 2013]
(a) x = y – z (b) z = x + y
(c) x = y + z (d) y = 2z – x

Answer 1

$\huge\bold\red{Answer:-}$

(c) x = y + z

Answer 2

$\huge{\underline{\mathbb{\red{Answer}}}}$

(c) x = y + z
