Web(a) Balance the redox equation. (hint: starting from the half equations) [4 marks] (b) A typical breathalyzer ampule contains 3.0 mL of a 0.25 mg/mL solution of potassium dichromate (K2Cr2O7) in 50% sulphuric acid solution (H2SO4). A person’s breath containing alcohol (CH3CH2OH) was sucked in which converted 90% of Cr2O7 2− to Cr3+ . WebThe rate equation becomes: Eq. 3 For a zero order reaction, x = 0 and the rate equation reduces to: Eq. 4 Integrating, we obtain: c = kt Eq. 5 In this case, a plot of concentration, c, versus time, t, will produce a straight line with the slope equal to the rate constant, k. For a first order reaction, x = 1 and the rate equation is: Eq. 6
