(a) To determine if the reaction is exothermic or endothermic, we examine the change in enthalpy (∆H). If ∆H is negative, the reaction is exothermic, meaning it releases heat. If ∆H is positive, the reaction is endothermic, meaning it absorbs heat.
In this case, the given data shows that the initial enthalpy (H1) is 50 kJ/mol and the final enthalpy (H2) is 30 kJ/mol. Since H2 is lower than H1, the change in enthalpy (∆H) is negative. Therefore, the reaction is exothermic.
(b) Without knowing the student's statement, it is not possible to agree or disagree. Please provide the student's statement for a response.
