Question

Consider the following reaction: 2SO2(g)+O2(g)→2SO3(g) If 285.0 mL of SO2 is allowed to react with 163.8 mL of O2 (both measured at 324 K and 54.7 mmHg ), what is the limiting reactant?
B.What is the theoretical yield of SO3?

C.If 188.0 mL of SO3 is collected (measured at 324 K and 54.7 mmHg ), what is the percent yield for the reaction? Express your answer using four significant figures.
