Problem: Given the balanced equation representing a reaction: H2 → H + H What occurs during this reaction? 1. Energy is absorbed as bonds are formed. 2. Energy is absorbed as bonds are broken. 3. Energy is released as bonds are formed. 4. Energy is released as bonds are broken.

FREE Expert Solution

We're being asked to determine what occurs during this reaction:

 H2 → H + H 


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
