Which row is correct for a chemical reaction in which ΔH is negative? | | bond energy change | type of reaction | |---|---|---| | A | energy of bonds broken greater than energy of bonds formed | endothermic | | B | energy of bonds broken less than energy of bonds formed | exothermic | | C | energy of bonds broken greater than energy of bonds formed | exothermic | | D | energy of bonds broken less than energy of bonds formed | endothermic |

1. Aenergy of bonds broken greater than energy of bonds formed; endothermic
2. Benergy of bonds broken less than energy of bonds formed; exothermic
3. Cenergy of bonds broken greater than energy of bonds formed; exothermic
4. Denergy of bonds broken less than energy of bonds formed; endothermic
