WebWhich of the following statements is true about the reaction below? H2O + CH3CO2H H3O+ + CH3CO2− ΔH = −10.3 kJ/mol; ΔS = −0.126 kJ/ (mol⋅K); ΔG = 27.26 kJ/mol It is exothermic. ΔH < 0, so the reaction is exothermic. WebIn this investigation, students classify chemical reactions as exothermic or endothermic. Next, students explore the relationship between an observed change in temperature and the classifica-tion of a change as chemical or physical. Objective Students will explore energy changes during chemical reactions, heat of reaction (∆H), and the
