Answer:
0.001341 mol/L s is the average rate from 8.0 to 20.0 seconds.
Explanation:
Average rate of the reaction =
=Average rate of the reaction during the given time interval.
= Change in concentration of reactant with respect to time.
= Change in time.
=Concentration of reactant at time
=Concentration of reactant at time
So, at the concentration of :
And at the concentration of :
The average rate of the reaction at given interval will be given as:
0.001341 mol/L s is the average rate from 8.0 to 20.0 seconds.

Answer=5×-10^8
CO₂ produced : 11.92 moles
<h3>Further explanation</h3>
Reaction
2C₂H₆ (g)+7O₂ (g) ⇒4CO₂ (g)+6H₂O(g)
mol ratio C₂H₆ : CO₂ = 2 : 4
moles of CO₂ :
