प्रश्न
On the basis of thermochemical equations (a), (b) and (c), find out which of the algebric relationships given in options (i) to (iv) is correct.
(a) \[\ce{C (graphite) + O2 (g) -> CO2 (g) ; ∆_rH = xkJ mol^{-1}}\]
(b) \[\ce{C (graphite) + 1/2 O2 (g) -> CO (g) ; ∆_rH = ykJ mol^{-1}}\]
(c) \[\ce{CO (g) + 1/2 O2 (g) -> CO2 (g) ; ∆_r H = zkJ mol^{-1}}\]
विकल्प
z = x + y
x = y – z
x = y + z
y = 2z – x

उत्तर
x = y + z
Explanation:
When we add equations (b) and (c) we will get equation (a) hence, Algebraic sum of y and z will give x, x = y + z.
