The modified chick's Watson equation derived from experiment during chlorination to determine the rate of kill using a sample of water whose temperature was 5' is as follows: No In 10.50125t Where t is in minutes. N: 1 Determine the required time to achieve 99.7% kill for a chlorine concentration of 0.08mg1 (3marks) Estimate the time it will take to achieve a similar kill at 17°C for the same water. Assume that the activation energy is 28,500J/mole and R, the gas constant is 8.3144J/molek in the vant Hoff- Arrhenius relationship tz E(T2-T1) RT,T2 (Smarks) lo
