A group of enterprising chemical engineering students are planning on scaling the production of beer to cover the increasing needs of the Engineering student functions using a 2000L vessel. One students home brew "recipe" calls for 2kg sugar per 20 L of water. As a simplification, assume the density of sugar is the same as water when mixed (to make a total volume of 22 L of solution). The overall reaction is: C6H12O6 2C2H5OH + 2CO2 The rate of reaction, ra is given below ra=-k(S)n where: ra is the rate of glucose (S, for sugar) reacted, in units of g/L/hr k = 2.2519 n = -0.04629 How do I calculate the initial concentration? explain
