A2 (g) + BD (g) AB (g) + AD (g) Question 5 (1 point) A chemist is about to start a gas phase experiment. They insert 1.00 mol of A2 (g) and 1.00 mol of BD (g) in a 10.0 L reaction vessel at room temperature (300 K). At this temperature, no reaction occurs between those two species. Assuming that the molar masses are 80 g/mol for A2 and 40 g/mol for BD, determine if the following statements concerning the gas mixture BEFORE any reaction takes place are correct or incorrect. The average kinetic energy of the A2 molecules is equal to the average kinetic energy of the BD molecules. The partial pressure of the BD molecules is smaller than the partial pressure of the A2 molecules. 1. Correct Every A2 molecule moves at the same molecular speed. 2. Incorrect The average molecular speed of the A2 molecules is smaller than the average molecular speed of the BD molecules. Some BD molecules move slower than some A2 molecules.
