The engineer charges ("fills") four reaction vessels with hydrogen chloride and oxygen, and lets the reaction begin. He then measures the composition of the mixture inside each vessel from time to time. His first set of measurements are shown in the table below. Predict the changes in the compositions the engineer should expect next time he measures the compositions. reaction compound pressure expected change in pressure vessel HCI 5.02 atm t increase OI decrease O (no change) 0, O (no change) 3.89 atm O t increase O I decrease A O I decrease O (no change) H,0 6.25 atm O t increase CI, OI decrease O (no change) 4.61 atm O t increase 6.23 atm O t increase O I decrease O (no change) HCI 0. 4.19 atm O t increase O I decrease O (no change) но O I decrease O (no change) 5.64 atm O t increase CI. 4.00 atm O t…arrow_forwardSulfur dioxide and oxygen react to form sulfur trioxide, like this: 2 SO2(g)+O2(9) 2 SO3(g) The reaction is exothermic.
