Add sample of NH4NO3(s) to water and measured the temperature over time. The data are shown in the graph above.
(a) What is the value of ΔT that the student should use to calculate q ?
(b) According to the graph, is the dissolution ofNH4NO3(s) endothermic or exothermic? Explain.
(c) Are the strengths of the interactions between the particles in the solute and between the particles in the solvent before the solute and solvent are combined greater than, less than, or equal to the strengths of the interactions between solute particles and solvent particles after dissolution? Explain.
