Solution
The correct option is B 200 molsec−1 To find out how much CO2 was produced, let us write down the rate law.
Let us calculate the amount of O2 produced in 10 seconds. That would just be 100 x 10 right? So, 1000 moles of O2 would be produced in 10 seconds. Fitting for a dragon!
Now, from the rate law we can see that the amount of CO2 would be 2 times that amount.
Therefore, rate of production of CO2 would be 200 mol sec-1
