For the following reaction: NO2(g) + CO(g) ->NO(g) + CO2(g), the rate law is: Rate = k [NO2]2.If 0.1 mole of gaseous carbon monoxide is added at constant temperature to the reaction mixture which of the following statements is true?
A.Both k and the reaction rate remain the same✓ Correct
B.Both k and the reaction rate increase
C.Both k and the reaction rate decrease
D.Only k increases, the reaction rate remain the
Explanation
k remains constant at constant temperature and CO does not effect the rate of reaction.
