Lets say
rate = k[A][B]n
(A is in excess, lets say at a concentration of 50mM)
My data includes the initial concentration of B, and the initial rate of reaction at that concentration
I can rewrite the rate equation as as:
rate = kapp[B]n
I then take the natural logarithm of this equation and plot a graph of ln(rate) against ln[B], the gradient will give me the value of n.
Am I right in thinking that the y intercept will give a value of kapp? And if it does, to determine the true rate constant do I just divide kapp by 50? If not, how do you determine the true rate constant?
