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

a) using "Euler's method" derive formulas to estimate the time required to achieve 95% conversion using excel

What is the formula for ra

Rate and concentration and conversion formula
