Comparing Rate Graphs

• Comparing for faster reaction:

  • Has a steeper gradient, shows faster reaction.
  • Takes less time to flatten out, shows faster reaction.
• • Two reactions shown produce same volume of product because the quantities of the reactants used are the same.
• • If quantity of the limiting reactant is changed, the volume of product formed will also change — E.G. if factor is halved, the reaction will produce half the volume of product.
• Two reactions

  
• • Comparing graphs show the differences in the rates of similar reactions - what is more effective for a faster rate.
• Comparing graph

  
• Calculating gradient of the tangent:

  • gradient = change in y / change in x
