Q. A small amount of sodium bromide (NaBr) is dissolved in a large amount of water. Imagine separating this process into the four stages sketched below. a) The enthalpy of the solution dHsoln is negative when NaBr dissolved in water. Use this information to list the stages in order of increasing enthalpy. b) Would heat be absorbed or released if the system moved from Stage A to B? c) What force would oppose or favor the system moving from Stage A to B? Check all that apply.
