A reaction at 1 bar is non-spontaneous at low temperature but becomes spontaneous at high temperature. Identify the correct statement about the reaction among the following :

The plot shows the variation of −$$ln$$ K_p versus temperature for the two reactions.

M(s) + $${1 \over 2}$$ O₂(g) $$ \to $$ MO(s) and

C(s) + $${1 \over 2}$$ O₂(g) $$ \to $$ CO(s)


Identify the correct statement :

The heats of combustion of carbon and carbon monoxide are –393.5 and –283.5 kJ mol^–1, respectively. The heat of formation (in kJ) of carbon monoxide per mole is :

The following reaction is performed at 298 K
2NO(g) + O₂ (g) $$\leftrightharpoons$$ 2NO₂ (g)
The standard free energy of formation of NO(g) is 86.6 kJ/mol at 298 K. What is the standard free energy of formation of NO₂(g) at 298 K? (KP = 1.6 × 10¹²)
