1. Integration can be used to compute how much mass M enters or leaves a reactor over a specified time period: 0 4 35 where Q is the volumetric flow rate, c is the concentration, and I, and t, equal the initial and final times, respectively 1, min Q, m/min c, mg/m3 9 10 4.8 20 5.2 55 30 5.0 52 35 4.6 401 40 4.3 37 45 4.3 50 5.0 34 32 Use Excel to numerically integrate this equation for the data given above to solve for M using the Trapezoidal Rule
