Question
ΔH for the following reaction is -180 kJ. Is this reaction endothermic or exothermic? 2 Na(s) + 2 H2O(l) –> 2 NaOH(aq) + H2(g) Group of answer choicesendothermicexothermic
Solution
This reaction is exothermic. The ΔH (change in enthalpy) of a reaction is negative when heat is released by the reaction, which is the definition of an exothermic reaction.
