In a chemical reaction A and B reacts to become E. C and D are the intermediaries of this reaction. The percent yields of the reaction are given below. What is the overall percent yield? A+B→C (Percent yield=70%)
C→D (Percent yield=90%)
D→E(Percent yield=50%)

The overall percent yield is calculated by multiplying the percent yields of each step: 70% * 90% * 50% = 0.7 * 0.9 * 0.5 = 0.315 or 31.5%.
