Question

Please answer quickly!! 1. Which of the following statements is true?

a. The breaking of bonds is exothermic, and therefore has a negative delta H value.
b. The breaking of bonds is exothermic, and therefore has a positive Delta H value.
6. The breaking of bonds is endothermic, and therefore has a negative Delta H value.
d. The breaking of bonds is endothermic, and therefore has a positive Delta H value

Answer 1

d

Step-by-step explanation:

a positive change in enthalpy is required to break a bond, while a negative change in enthalpy is accompanied by the formation of a bond. Bond breaking in endothermic because it requires energy, therefore delta H is positive.
