· An exothermic reaction means energy is
given out to the surroundings so the
overall enthalpy change is negative.
· Examples of exothermic reactions:
· CH4(g) + 2O2(g) CO2(g) + 2H2O(l)
· Oxidation of carbohydrates like glucose:
· C6H12O6…read more
· Energy is released when bonds are
formed so the H is negative and the
reaction is exothermic.
· Stronger bonds release more energy when
they form so their bond enthalpy is higher.…read more
