Calculate the change in H, change in G and K (at 298) for the production of ozone from oxygen: 3O2(g) goes to 2O2(g) at 30 km above the surface of the earth the temperature is about 230 K and the partial pressure of oxygen is about 1.0 x 10^-3 atm. Estimate the partial pressure of ozone in equilibrium with oxygen at 30 km above the earth's surface. Is it reasonable to assume that he equilibrium between oxygen and ozone is maintained under these conditions? explain
How many moles and liters of gas would be produced by reacting 55.7 g of NaHCO3 with excess vinegar. Assume the reaction releases all the gas theoretically possible, and the reaction takes place at 22 C and 1 atm. NaHCO3(s) + CH3COOH(aq)-> CO2(g) ..
