Question

Which of the following is true for the reaction $C(g) + 4H(g) \rightarrow CH_{4}(g);\Delta H = - 166kJ$⇌$C - H$ at $H - H$ and 1 atmosphere.

• A. $mol$
• B. $Cl - Cl$
• C. $240kJmol^{- 1}.\Delta H$
• D. $HCl$

Answer 1

Answer: (D)

$HCl$

Answer 2

At equilibrium, $H - H$ = 0

Hence 0 = $Br - Br$ or $HBr$.
