Question

Consider the following reversible reaction.Upper (s) plus upper O subscript 2 (g) double-headed arrow upper C upper O subscript 2 (g).What is the equilibrium constant expression for the given system?

Answer 1

Given the reaction:

C + O2 ⇄ CO2

We can find the equilibrium constant (Keq) using the following:

`k_(eq)=([products])/([reactants])`
`k_(eq)=([products])/([reactants])\Rightarrow k_(eq)=([CO_2])/([C][O2])`

Therefore the answer is letter A
