1. Which situation describes an exothermic
reaction?
(a) The energy that is released to form the
product bonds is greater than the energy that
is used to break the reactant bonds.
(b) The energy that is released to form the
product bonds is less than the energy that is
used to break the reactant bonds.
(c) The energy that is released to form the
product bonds is equal to the energy that is
used to break the reactant bonds.
(d) The energy that is used to break the product
bonds is greater than the energy that is
released to form the reactant bonds.
(e) The energy that is used to break the product
bonds is less than the energy that is released
to form the reactant bonds.
