📊 Comparing Reaction Graphs

When you change rate factors:

  • Faster reaction: Steeper initial curve, reaches plateau sooner
  • Same amount of limiting reactant: Same final amount of product (same plateau height)
  • More reactant: Higher plateau (more product made)

Higher temperature

Steeper curve, same final volume

Higher concentration

Steeper curve, same final volume (if same moles)
