Neco Model Questions Vol1 2023 Chemistry Question 2
Practice objective / multiple choice question 2 from the 2023 Neco Model Questions Vol1 Chemistry examination.
The Henry's law constant for carbon dioxide at 25°C is \(3.3\times10^{-2}\) mol·L^{-1}·atm^{-1}. The enthalpy of solution of CO_2 is \(-19\) kJ·mol^{-1}. Calculate the concentration of dissolved CO_2 (in mol·L^{-1}) in water at 35°C when the partial pressure of CO_2 above the water is \(4.0\times10^{-4}\) atm. (Assume the van't Hoff equation applies and use \(R = 8.314\) J·mol^{-1}·K^{-1}).
