Neco Model Questions Vol1 2024 Chemistry Question 24
Practice objective / multiple choice question 24 from the 2024 Neco Model Questions Vol1 Chemistry examination.
The esterification of propanoic acid with ethanol has an equilibrium constant \(K = 4.0\) at \(25^{\circ}\text{C}\) (298 K). The standard enthalpy change for the reaction is \(\Delta H^{\circ} = -25\ \text{kJ mol}^{-1}\). Assuming \(\Delta H^{\circ}\) remains constant over the temperature range, at what temperature (in kelvin) will the equilibrium constant double (i.e., become 8.0)? Use the van't Hoff equation.
