For the reaction `CH_(4(g))+2O_(2(g))hArrCO_(2(g))+2H_(2)O_(l)`:
(`DeltaH=-170.8 kJmol^(-1)`). Which of the following statement is not true?

Options

A. Addition of `CH_(4(g))` or `O_(2(g))` at equilibrium will cause a shift to the right
B. The reaction is exothermic
C. At equilibrium, the concentrations of `CO_(2(g))` and `H_(2)O_((l))` are not equal
D. The equilibrium constant for the reaction is given by `K_p=([CO_2])/([CH_4][O_2])`

Answer

D

Explanation

`K_p=([CO_2])/([CH_4][O_2]^2)`
