Calculate the equilibrium constant for the following reaction at 37 °C. AGO-3.13 kJ/mol Fumarate + H2O → Malate Type your answer...

How is the pH scale defined? What range of pH values corresponds to acidic solutions? What range corresponds to basic solutions? Why is pH = 7.00 considered neutral? When the pH of a solution changes by one unit, by what factor does the hydrogen ion concentration change in the solution? How is pOH defined? How arc pH and pOH for a given solution related? Explain.

Obtain the equilibrium constant for the reaction HCN(aq)H+(aq)+CN(aq) from the following HCN(aq)+OH(aq)CN(aq)+H2O(l);K1=4.9104H2O(l)H+(aq)+OH(aq);K2=1.01014

Given that the Gf for Pb2+(aq) and Cl-(aq) is -24.3 kJ/mole and -131.2 kJ/mole respectively, determine the solubility product, Ksp, for PbCl2(s).
