When a sample of `NO_(2)` is placed in a container, this equilibrium is rapidly estabilished.
`2NO_(2)(g) hArr N_(2)O_(4)(g)`
Iff this equilibrium mixture is a darker colour at high temperatures annd at low pressure, which of these statements about the reaction is true?

A

Formation of `N_(2)O_(4)` from `NO_(2)` is exothermic and `N_(2)O_(4)` is darker in colour than `NO_(2)`

B

Formation of `N_(2)O_(4)` from `NO_(2)` is exothermic and `N_(2)O_(4)` is darker in colour than `NO_(2)O_(4)`

C

Rate of transformation of `NO_(2)` to `N_(2)O_(4)` is equal to the rate of transformation of `N_(2)O_(4)` to `NO_(2)` at equilibrium

D

There is no change in the concentrations, colour, vapour density of reaction mixture, at equilibrium
