▪ shed energy, release heat, temperature of the surroundings increases▪ entails bond development (for step change: gas → fluid → solid)▪ ΔH isnegative
• Endothermic reactions
▪ gain/requires energy, absorbs heat, temperature of the next site decreases▪ involves breaking bonds (for phase change: heavy → fluid → gas)▪ ΔH ispositive
Analyzing process given:
Which one of the following processes is endothermic?
a. 2 H2 (g) + O2(g) → 2 H2O (g)
