(c) A mixture (blend) of tertiary butyl alcohol, coker gasoline, and FCC gasoline is given in Table Q2.1 below: (i) Determine the volume fractions of the various components in the blend (at least 4 decimals, e.g. X.XXXX ). [3 marks] (ii) Calculate the Research Octane Number (RON) of the blend by linear mixing of RON (to 2 decimals). [2 marks] (iii) Determine RON blending indices for each component ('BlRON') according to equations (1-3) below (to 2 decimals). [3 marks] (iv) Determine the mixture's blending index and its RON using Table Q2.2, which used Eq. 2 to find the data shown. Calculate the \% error between the RON found in (ii) and that found in (iv). [4 marks] Table Q2.2 Relevant extract of table of RON vs. BIRON For 11RON76 268.64(RON/100)5 Eq(1)
