Problem- Define activation energy. how does activation affect rate constant? How does temperature affect the rate of a reaction and how does temperature relate to activation energy?
Rewrite your answer from the stating and prove each step carefully.
The Henry's law constant of CO2 in water at 250C is 0.167x109Pa. If the partial pressure of CO2 over water is 1 bar, calculate the solubility in moles per Liter of CO2 in water at 250C. Assume the number of moles of CO2 in solution is negligible c..
