When a sample of `NO_(2)` is placed in a container, this equilibrium is rapidly estabilished.
`2NO_(2)(g) hArr H_(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

The reaction is exothermic and `NO_(2)` is darker in colour than `N_(2)O_(4)`

B

The reaction is exothermic and `N_(2)O_(4)` is darker in colour than `NO_(2)`

C

The reaction is endothermic and `NO_(2)` is darker in colour than `N_(2)O_(4)`

D

The reaction is endothermic and `N_(2)O_(4)` is darker in colour than `NO_(2)`
