Question

In the oxidation of carbon monoxide to carbon cloxide, which maclant is consurred at the hight rate? What is the numerical ratio of rate of change in the concentration of CO2 to the rate of change in the concentration of O2? The gas NO reacts with H2, forming N2 and H2O: What is the instantanous rate of charge of [NO2] at t = 2000 s in the experimetn linal producst the data in the label below? The reactium is Nitric oxide reacts rapidly with unstable nitrogen trioxide (NO3) to form NO2. Caclculate the numeric: value of the conslant for the above reaction from the data in the lable below Experimental evidence shows that in the reaction the reaction rate depencs onl y on the concentration of NO2. Determine whether the reaction is first or second order in NO2, and calculate the rate constant from the data obtained at 488K in the table below.

Explanation / Answer

1)CO is consumed in higher rates

numerical ratio is 2:-1

2)Rate of change of N2=-1/2*rate of change of NO=11.2M/s

Rate of change of H2O=-rate of change of NO=22.4M/s

3)[NO]t = [NO]oe^(-kt)

at t=0 [NO]=0.01 =>[NO]o = 0.01

at t=205 [NO]=0.009 =>0.009=0.01*e^(-k*205)

=>k=1/205*ln(0.01/0.009) =5.14*10^-4 /sec

So [NO]2000 = 0.01*e^(-5.14*10^-4*2000)=0.00357 M

=>[NO2]2000 =0.01-0.00357=0.00643 M
