Notice that in this particular reaction, the numerical

coefficients are all “1” indicating 1 mole of each

substance.

IF, the numerical coefficient was 2 or 3 (or whatever),

in determining the amount of energy needed or released

(using the bond energy table), you would have to multiply

that number by the numerical coefficient.

For example, let’s say that you had 2 moles of methane

in reaction where a C-H bond was broken:

2(414 kJ) = 828 kJ
