Lower yield.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

you get less products.

you also have more unreacted reagents left to seperate from your reaction mixture.
