A sealed, flexible container holds 92.5 mL of xenon gas at 15.0 C. Find the temperature needed (in degrees Celsius) to result in the container doubling its volume at a constant pressure.

The activation energy for the reaction no2(g)+co2(g)⟶no(g)+co(g) is ea = 300 kj/mol and the change in enthalpy for the reaction is δh = -100 kj/mol . what is the activation energy for the reverse reaction?
