An endothermic reaction takes in heat from its surroundings. One example of a spontaneous endothermic reaction is an ice pack that doesn't have to be kept in the freezer. When the ice pack is struck with your palm the membrane is broken and the salt is dissolved in the water. The equation would be NH4NO3 plus H2O is equal to NH4 plus NH3.
