Question

The reaction of CH4 and O2 to form CO2 and H20 is

           a) An example of a higher exergonic reaction

           b)  An example of a case where we know the reason thefree energy of the reactants is high and that of the products islow.

           c)   An example of reactants having high potentialenergy and products low potential energy.

           d)   An example of a reaction that is similar tothat which occurs in a combustion energy (car energy); nonpolarbonds are broken and converted to polar bonds plus energy.

           e) a-e are all correct.

Explanation / Answer

a) An exergonic reaction, like an exothermic reaction, is anythat produces heat - burning produces heat, so this is true.
b) This is true, see c
c) Any reaction that produces heat needs to get it fromsomewehere, and it is from the potential energy of bonds - this istrue
d) This is ture - it is te same as choice c
Therefore, the answer is (e) all of the above
Hope that helps
