CgH8(g) + 5 O2(g) - 4H2O(g) + 3 CO2(g) The volumes of the reactants and products of this reaction are measured under the same conditions. What is the total number of liters of CO2
produced when 150 liters of O2 reacts completely with C3H8?
A) 3.0
B) 90
C) 150
D) 250

Can someone me with questions 15 to 17 plz.

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l.s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?

Can someone me with 3 and 4 plz. this is for masteries test.
