... Essential idea: Many reactions are reversible. These reactions will reach a state of equilibrium when the rates of the forward and reverse reaction are equal. The position of equilibrium can be controlled by changing the conditions. Nature of science: Obtaining evidence for scientific theories—isoto ...

... b. Example: CH4 + O2 CO2 + H2O + ENERGY i. This is an EXOTHERMIC reaction because it releases energy as heat c. Example: N2O4 + ENERGY 2NO2 i. This is an ENDOTHERMIC reaction because energy must be absorbed by N2O4 in order to form NO2 2) Molecules and atoms must come into contact for them to ch ...
