Unformatted text preview: 07.02.1 07.02 Trapezoidal Rule for Integration-More Examples Chemical Engineering Example 1 In an attempt to understand the mechanism of the depolarization process in a fuel cell, an electro-kinetic model for mixed oxygen-methanol current on platinum was developed in the laboratory at FAMU. A very simplified model of the reaction developed suggests a functional relation in an integral form. To find the time required for 50% of the oxygen to be consumed, the time,   s T is given by dx x x T                     6 6 10 61 . 10 22 . 1 11 7 10 316 . 2 10 3025 . 4 73 . 6 a) Use single segment Trapezoidal rule to find the time required for 50% of the oxygen to be consumed. b) Find the true error, t E , for part (a). c) Find the absolute relative true error, t  , for part (a).
