Rate concentration graphs

• 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
