The relationship between the Monod rate constant, k and the rate constant observed due to waste accumulation kobs is ____

kobs = k (1-\(\frac{C_R}{C_R^*})^\frac{1}{n}\)

kobs = k (1-\(\frac{C_R}{C_R^*}\))n

kobs = k (1-\(\frac{C_R}{C_R^*})^\frac{1}{n}\)

k = kobs (1-\(\frac{C_R}{C_R^*}\))n

kobs = k (\(\frac{C_R}{C_R^*}\))nCR* is the concentration of R where cell activity stops and n is the order of product poisoning.
