If the concentration of Ti2+ is changed from 1.0 M to 0.1 M in the galvanic cells above, what will happen to the observed cell voltages in galvanic cells 2 and 3?

If the concentration of Ti2+ is changed from 1.0 M to 0.1 M in the galvanic cells above, what will happen to the observed cell voltages in galvanic cells 2 and 3? Correct Answer The voltage in both galvanic cells 2 and 3 will increase.

Since the standard cell voltage is positive, we know that the equilibrium constant must be greater than 1. If conditions change so Q is greater than 1, the system is approaching equilibrium and the voltage is expected to decrease. If Q is less than 1, the voltage will increase. In this case, Q = 0.1, so the voltage will increase in galvanic cells 1 and 3.

Select the correct answer:
A solid-oxide fuel cell is fed with carbon monoxide and reacts with air to produce CO2. This reaction will produce 2 electrons which are used to power an electric circuit external to the fuel cell. The reaction equation is shown below: 2CO(g) + O2(g) -> 2CO2(g) ΔHr° = -565.96 kJ/mol This reaction does not occur for other types of fuel cells which use a catalyst, such as polymerelectrolyte membrane or phosphoric-acid fuel cells. The presence of carbon monoxide on the anode side of these types of fuel cells will cause catalyst poisoning, reducing the efficiency and voltage of the fuel cell. Determine the rate of enthalpy change for a carbon dioxide production rate of 208 mol/hr. The extent of the reaction occurring in the fuel cell can be obtained by the following equation: where:
Which of the following is a correct method to calculate the EMF of a galvanic cell? + b) Standard EMF of the cell = – c) E°cell = E°cathode – E°anode d) Standard EMF of the cell = +
