For a certain chemical reaction, Qc = 0.2 and Kc = 0.2. Under these conditions, which of the following is true? For full credit, mark all that are true and none that are false. Select one or more: $\Delta G = 0$ $\Delta G < 0$ $\Delta G > 0$ $\Delta G^\circ = 0$ $\Delta G^\circ < 0$ $\Delta G^\circ > 0$

Step 1
Step 1: The relationship between the Gibbs free energy change ($\Delta$G) and the equilibrium constant (K) is given by the following equation: $\Delta$G = -RTlnK where R is the ideal gas constant, T is the temperature in Kelvin, and K is the equilibrium constant. Show more…

1) A chemical reaction that is spontaneous (in the way that it is written, from "left to right") will have a delta G value that is negative, while a chemical reaction at equilibrium will have a delta G value equal to zero. True or false? 2) The reaction quotient Q, is computed from concentrations or partial pressure of the reactants and products and is unitless. True or False? 3) One can expect a very spontaneous reaction to process a negative standard Delta G value and large K value True or false?

All of the following statements are TRUE excepts? If delta G> 0, then a reaction is not spontaneous If delta G= 0, then delta S = delta H/T If delta G= delta G, K = 1 If delta G= delta G, Q =1

The statements in the tables below are about two different chemical equilibria. The symbols have their usual meaning, for example stands for the standard Gibbs free energy of reaction and stands for the equilibrium constant. In each table, there may be one statement that is false because it contradicts the other three statements. If you find a false statement, check the box next to it. Otherwise, check the "no false statements" box under the table.
