The pH of rainwater in Parit Raja area can be computed as: pH=-log,[H] where [H') is the molar concentration of hydrogen ions. The chemistry of rainwater is also governed by the nonlinear system of equations as follows: ${[H*])= 5.474x10-"[H*+5.487x10 *[H*]+10-4[H*]-[h*j (a) Based on the obtained third-order polynomial, determine the pH of rainwater in Parit Raja area using Secant method, with starting interval [2,12]. Iterate until 10h-iteration. (15 marks)
