Question
at room temperature chlorine is a gas, bromine is a liquid and iodine is a solid at room temperature chlorine is a gas, bromine is a liquid and iodine is a solid at room temperature chlorine is a gas, bromine is a liquid and iodine is a solid at room temperature chlorine is a gas, bromine is a liquid and iodine is a solid A slush of liquid water and ice crystals is at equilibrium at 0 °C. If a small amount of heat is removed so tha more ice is formed, the system will experience: a. a temperature rise since lattice energy of ice is exothermic. b. a change in vapor pressure over the mixture c. a temperature lowering since more ice produces a colder system. 3. d. no temperature change.Explanation / Answer
The equilibrium reaction may be written as
Ice + Energy <======> Water
The fusion of ice is an endothermic reaction, since heat must be given to melt ice to water. Consider heat as a reactant of the equilibrium. When heat is removed, the equilibrium will shift to the left, producing more ice. Removal of heat leads to a lowering in temperature, hence (a) is false. Since the temperature falls, therefore, (c) is the correct answer.
