In a gaseous 2L reaction system 2.00 mol of methane, CH4(g) is added to 10.00 mol of chlorine, Cl2(g). At equilibrium the system contains
1.40 mol of chloromethane, CH3Cl(g) and some hydrogen chlorine, HCI(g).
a) State a balanced chemical equation for this equilibrium.
b) Compute the amount of each substance at equilibrium.
The vapor pressure of water at 25 degrees C is 23.8 torr. Determine the mass of glucose (MW=180.0 g/mol) needed to add to 500.0 g of water to change the vapor pressure to 23.1 torr.
