Problem 2 - The reaction between ammonia and formaldehyde to produce hexamine is 4NH3 + 6HCHO (CH2)6N4 + 6H2O A 0.5 L CSTR reactor was used for the reaction. Each reagent is fed into the reactor in separate streams, at a flow rate of 1.5-10-3 L/s each. The concentrations of ammonia and formaldehyde in the feed are 4.0 mol/L and 6.4 mol/L, respectively. Calculate the concentrations of ammonia and formaldehyde in the outgoing stream. The reaction rate and rate constant equations are: (-ra) = kcCB; k = 1.42 10exp(-3099) Where A is ammonia and B is formaldehyde. T
