If 0.400 moles CO and 0.400 moles O2 completely react, 17.604 grams of CO2 would be produced.
First, let us look at the balanced equation of reaction:
According to the equation, the mole ratio of CO and O2 is 2:1. But in reality, the mole ratio supplied is 1:1. Thus, CO is the limiting reactant while O2 is in excess.
Also from the equation, the ratio of CO consumed to that of CO2 produced is 1:1. Thus, 0.400 moles of CO2 would also be produced from 0.400 moles of CO.
Recall that: mole = mass/molar mass
Therefore, the mass in grams of CO2 that would be produced from 0.400 moles can be calculated as:
Mass = mole x molar mass
= 0.400 x 44.01
= 17.604 grams

Answer:
A) 0.065 M is its molarity after a reaction time of 19.0 hour.
B) In 52 hours will react 69% of its initial concentration.
Explanation:
The reaction is first order in :
Initial concentration of =
a) Final concentration of after 19.0 hours=
t = 19.0 hour = 19.0 × 3600 seconds ( 1 hour = 3600 seconds)
Rate constant of the reaction = k =
The integrated law of first order kinetic is given as:
0.065 M is its molarity after a reaction time of 19.0 h.
b)
Initial concentration of =
Final concentration of after t =
Rate constant of the reaction = k =
The integrated law of first order kinetic is given as:
t = 185,902.06 s = ≈ 52 hours
In 52 hours will react 69% of its initial concentration.
