▪ lose energy, releases warmth, temperature of the surroundings increases▪ entails bond development (for phase change: gas → liquid → solid)▪ ΔH isnegative

Endothermic reactions

▪ gain/calls for power, absorbs heat, temperature of the surroundings decreases▪ involves breaking bonds (for phase change: solid → liquid → gas)▪ ΔH ispositive

Examining procedure given:


Which one of the adhering to procedures is endothermic?

a. 2 H2 (g) + O2(g) → 2 H2O (g)
