## Description

In a biochemical equilibrium reaction taking place in solution, substances A and B react to form products C and D. The equilibrium constants (k) is 0.36 at 298k and at the start the concentration of A is 0.1 mol and B is 0.05 mol in solution of 500cm3. Use a quadratic equation to find the value of the products C and D.

Q4 In a biochemical equilibrium reaction taking place in solution, substances A and B react to form products C and D. A+B=C+D The equilibrium constant for the reaction, K, is given by K = [CID] where [A], [B], [C], [D] are the concentrations of each reactant and product [A][B] and at 298K, K = 0.36 At the start of the reaction, there are 0.1 mol of A and 0.05 mol of B in solution in 500 cm? Once equilibrium is established, there are x moles of C and x moles of D. i) By writing a suitable expression for K, derive and solve a quadratic equation in x to find the number of moles of each product in solution. ii) Sketch the graph for the quadratic equation. iii) Use differential calculus to find the stationary point and explain whether it is a maximum or minimum. iv) Find the equation of the tangent to the curve when the number of moles of product is 0.02 mol.
