Question

Eoghan runs a reaction in a beaker and notices that, during the reaction, the temperature in the beaker fell from 23.8 °C to 4.2 °C. Predict the sign of $\Delta H$ for the reaction, and determine if the reaction is exothermic or endothermic. A $\Delta H = +$, exothermic B $\Delta H = +$, endothermic C $\Delta H = -$, exothermic D $\Delta H = -$, endothermic
