I need the answer as soon as possible

Q.5. In modelling the effect of an impurity on crystal growth, the following equation was derived: (G-G/G-G)= 1/K.Ch Where C is impurity concentration, G is limiting growth, Go is the growth rate of crystal with no impurity present, and K and m are model parameters. In a particular experiment, G,=3.00 * 10' and GL = 1.80*10, Growth rates are measured for several impurity concentration C with the following results: C(ppm) 50.0 G(mm/min) *103 2.5 75.0 2.20 100.0 2.04 125.0 1.95 150.0 1.90 (a) Determine K, and m, giving both numerical values and units. (b) A solution is fed to a crystallizer in which the impurity concentration is 475 ppm, Estimate the expected crystal growth. Then state why you would be extremely skeptical about the result
