Areaction requires 22.4 l of gas at stp. you have 45.0l of gas at 100 kpa and 373 k which of the following statements is true? the constant is 8.3 l-kpa/mol-k

At STP, 1 mole has occupies a volume of 22.4 L. So n = 1. We have 45.0L of gas at 100 kPa and 373 K we plug in these given values of V, R, P and T to the ideal gas law equation: PV = nRT and solve for n.  (We use 8.314 L kPa/ mol*K as the gas constant). The n value we got is 1.45, exceeding the 1 mole minimum requirement.

Thus the answer is: "You will have an excess of gas and the reaction will occur. "

See if you get more than 1 mole or less.
