Reaction Yield (HSC SSCE Chemistry): Flashcards

$\frac{\text{Actual mass}}{\text{Theoretical mass}} \times 100\%$

Max amount of product if reaction is 100% efficient

Amount of product really obtained from reaction

No effect on yield, only increase rate to reach equilibrium

Shifts equilibrium right, favours forward reaction

Ammonia from nitrogen and hydrogen gases

Sulfuric acid ($\text{H}_2\text{SO}_4$)

Reactant that runs out first, limiting product formation

$\frac{\text{Mass of product}}{\text{Total mass}} \times 100\%$

Lower temperature favours forward reaction, increases yield
