Suppose two balloons are separated by a tube with a tap in between the tap is initially closed. one of the balloons (V=4L, P=0.5atm) contains NO and in the other balloon (V=2L, P=1 atm) there is oxygen. when the faucet is opened we have the following reaction: 2NO(g) + O2(g) >2NO2(g) Assuming that the temperature remains constant and equal to 298K, determine the partial pressures and the molar fraction of each gas.
