During an exothermic reaction, δh for the reactants was 890 kj/mol. which of the following statements is correct about the δh for the products?
a. it is less than 890 kj/mol because the amount of energy required to break bonds is less than the amount of energy released in forming bonds.
b. it is less than 890 kj/mol because the amount of energy required to break bonds is greater than the amount of energy released in forming bonds.
c. it is greater than 890 kj/mol because the amount of energy required to break bonds is less than the amount of energy released in forming bonds.
d. it is greater than 890 kj/mol because the amount of energy required to break bonds is greater than the amount of energy released in forming bonds.
