Answer: The volume of product formed is 0.26 L
Explanation:

As
is the the excess reagent,
is the limiting reagent as it limits the formation of product.
According to stoichiometry :
2 moles of
give = 2 moles of 
Thus 0.01 moles of
will give =
of 
According to ideal gas equation:

P = pressure of gas = 101.325 kPa = 1 atm
V = Volume of gas = ?
n = number of moles = 0.01
R = gas constant =
T =temperature =


Thus the volume of product formed is 0.26 L
Energy cannot be created or destroyed, so the answer would be c.) not a or b.
Hope this helps!
