When a sample of `NO_2` Is placed in a container, this equilibrium is rapidly established. If this equilibrium mixture is of a darker colour at high temperatures and at tow pressures, which of these statements about the reaction is true?
`2NO_2(g) iff N_2O_4(g)`

A

The reaction is exothermic and `2O_4` is darker in colour than `NO_2`

B

The reaction is exothermic and `NO_2` Is darker in colour than `N_2O_4`

C

The reaction is endothermic and `NO_2` is darker in colour than `N_2O_4`,

D

The reaction is endothermic and `N_2O_4`, is darker in colour than `NO_2`
