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).

Calculate K for the reactions in Question 1.

For each of the following statements, indicate whether it is true or false and offer a brief explanation of your choice. a. For the endothermic reaction 2H,O = H,O* + OH at 25°C K= 1.0 x 10-14. The pH of water at 50°C is greater than 7. b. Consider the following reaction at equilibrium in a container of flexible volume: + Cl = PClgr The addition of an inert gas to the container will result in more PCI being made. (Äsume ideal gas behaviour.) PCI3) c. For a reaction in the gaseous state the numerical values of K¸ and K, are always different.

2MnO4−+5H2C2O4+6H+⟶2Mn2++10CO2+8H2O Reaction : Permanganate Ion Reduced by Oxalic Acid If you increase the concentration of oxalic acid in an experiment, what will the molecules and ions be doing? (Simply trying to determine how it will be effected because I don't understand what it would be doing. In the experiment I did, it took longer to notice any changes occur in the color of the test I was doing. )

Refer to the attached photo. Thank you!

The equilibrium constant for the acid ionization of mercaptoethanol (HSCH2CH2OH) is HSCH2CH2OH(aq) = H+(aq) + SCH2CH2OH-(aq)               k= 1.91 x 10-10 Which of the following is/are true regarding this equilibrium? And why? 1. The reaction is product-favored. 2. The reaction is reactant-favored. 3. Equilibrium lies far to the right. 4. Equilibrium lies far to the left.

hát is the équilibrium constant for the following reaction
