Entropy and equilibria 0.0 / 5 ? EngineeringEquilibrium thermodynamicsUniversityNone Created by: OmololaS15Created on: 03-01-19 18:36 How can the entropy of a protein be altered? Breaking the protein increases the ΔS as there is an increase in the number of ways you can arrange the system. 1 of 10 Define 'Denaturation' The conversion of an ordered protein into a disordered one. 2 of 10 Give an equation for K of a gas being dissolved in water K = a_aq *a^-1_g = (c_s/c。) *(p。/p_s) ] where c_s/p_s = concentration/pressure of substance; 3 of 10 State an equation with G,Q and K Δ_rG = -RTln(K/Q) 4 of 10 Describe a weak acids Partially dissociates in water. 5 of 10 Give an expression for K_a K_a = a_H *a_A*a^-1_HA ~~ [H+][A-]/[HA]c。 6 of 10 What is the relationship between K_a and acidity level of a substance? The lower the K_a the lower the acidity of the solution. 7 of 10 How is pH calculated? pH = - log_10 [H+] 8 of 10 What is assumed when working out solid solubility? The activity of the solid is = ONE with dilute ions, an ideal solution is created 9 of 10 Give an expression for K_sp e.g for Cu_3(PO_4)_2 (s) k_sp = (a_Cu^2+)^3(a_PO_4^3-)^2(a_solid)^-1 = [Cu^2+][PO_4^3-]/c。^5 10 of 10
