Actually, Henry's Law is an empirical value. It means that it was not obtained out of raw calculations or correlations. This was gathered from experimental results. Hence, you can search its data. At standard temperature of 25°C (298 K),
k = k°e^[2400(1/T - 1/T°)], where k° = 29.4 L·atm/mol
Substituting the values so that T would be in 20°C or 293 K,
k = (29.4 L·atm/mol)e^[2400(1/293 - 1/298)]
k = 33.7 L·atm/mol
Answer:
Initial rate method
Explanation:
The initial rate of the reaction is dictated by the different concentrations of one reactant, while other reactants remain constant.
The number is 25. The square root of 25 is 5 and 5x2 is 10 and then 10+5 is 15
