Rate concentration graphs

Cards (6)

  • Zero order 

    Rate doesn’t depend on the concentration. the line is parallel to the x axis
  • First order
    The rate is proportional to the concentration
  • Second order
    The rate is proportional to the square of concentration
  • Zero order
    K is equal to the intercept on the y-axis
  • First order
    K is equal to the gradient of the line
  • Second order
    cant obtain k from this. must plot a second graph of rate vs conc2 then find the gradient of the line
