Physical systems may be described by systems of differential equations with more than one dependent variable appearing in multiple ODEs. When a chemical substance X is broken down into a product P by means of an enzyme E, the process may be described by the Michaelis-Menten reaction X + E  ⇌  Y  ⇌  P + E where Y is a combined substance of X and E, and the enzyme is released at the end of the process to be used again. The differential equations governing the quantities X(t) and Y(t) are given by X ′  =  − k1 (E0 − Y ) X  +  k−1YY ′  =  k1 (E0 − Y ) X  −  (k−1 + k2)Y where E0 is the initial concentration of enzyme E. Then (E0 − Y ) represents the amount of enzyme that is not tied up in Y, and so is available for reacting with X. Starting with initial concentrations of X(0) = 0.8 and Y(0)  =  0, use Euler's method with a step size of 0.1 to determine the amount of substance X(t) still remaining at times t  =  5 and  t  =  10. Use the parameters E0  =  0.5k1  =  0.6k−1  =  0.3k2  =  0.5

Consider the following anaerobic fermentation reaction of glucose: C6H12O6(aq) → 3CH4(g) + 3CO2(g) ΔG° = -418 kJ If ΔG° for CH4 is -50.8 kJ/mol and -394.2 kJ/mol for CO2, what is ΔG° for C6H12O6?
