We’re being asked to determine if the dimerization of water is exothermic or endothermic using the Kp given and temperature
According to Le Chatelier’s Principle, if a system (chemical reaction) is at equilibrium and we disturb it, then the system will readjust to maintain its equilibrium state.
The dimerization of water will appear as:
Water molecules in the atmosphere can form hydrogen-bonded dimers, (H2O) 2. The presence of these dimers is thought to be important in the nucleation of ice crystals in the atmosphere and in the formation of acid rain.
The K p for water dimer formation in the gas phase is 0.050 at 300 K and 0.020 at 350 K. Is water dimer formation endothermic or exothermic?
