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:
With reference to 'fuel cells' in which hydrogen rich fuel and oxygen are used to generate electricity. Consider the following statements.

Select the correct answer:
Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Read the statements and choose the correct answer:
Assertion (A) The nominal interest rate comprises of a real interest rate and an expected rate of inflation and it adjusts when the inflation rate is expected to change. Hence, in the perfect international capital markets, real rate of returns are equal in the two countries.
Reason (R) The international fisher effects states that the nominal interest rate differential must be equal to the expected inflation rate differential In the two countries.
