A 7.75-L container holds a mixture of two gases at 37 °C. The partial pressures of gas A and gas B, respectively, are 0.209 atm and 0.735 atm. If 0.130 mol a third gas is added with no change in volume or temperature, what will the total pressure become?
Consider the following reaction at equilibrium: 2CO2(g) 2CO(g) + O2(g) Change in H degree = -514kJ a) increase partial pressure of CO2 at equilibrium
