A reaction requires 22.4 L of gas at STP. You have 30.5 L of gas at 101.5 kPa and 373 K. Which of the following statements is true? (Use the ideal gas law: PV = nRT where R = 8.31 L-kPa/mol-K.) A. You will have excess gas for the reaction. B. You will have enough gas for the reaction. C. You do not have enough gas for the reaction. D. Given this information, you cannot tell if you have enough gas for the reaction.

STP conditions are 101.3 kPa and 273 K. We calculate volume at the given conditions assuming 1 mole of gas.
(P₁V₁)/T₁ = (P₂V₂)/T₂
V₂ = (101.3 * 22.4 * 373) / (273 * 101.5)
V₂ = 30.5 L
Therefore, we have enough gas for the reaction. The answer is B.

Answer:

You will have an excess of gas and the reaction will occur.
