Problem: How should the baking of a pizza be categorized?a. as an exothermic process because the dough releases heatb. as an endothermic process because the dough releases heatc. as an exothermic process because the dough absorbs heatd. as an endothermic process because the dough absorbs heat

FREE Expert Solution

Recall that:

Exothermic reactions

lose energy, releases heat, temperature of the surroundings increases
▪ involves bond formation (for phase change: gas → liquid → solid)
ΔH is negative

Endothermic reactions

gain/requires energy, absorbs heat, temperature of the surroundings decreases
▪ involves breaking bonds (for phase change: solid → liquid → gas)
ΔH is positive
