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)` of the reaction is: `K_(p) = ((P_(CO_(2))^(')))/((P_(CH_(4))^('))(P_(O_(2))^(')))`
