Which of the following is/are correct regarding the measurement of the rate of oxidation?

Which of the following is/are correct regarding the measurement of the rate of oxidation? Correct Answer Weight gain per unit area of metal is the measure of the rate of oxidation

Rate of oxidation is usually measured and expressed in terms of weight gain per unit area of metal. As oxidation results in the conversion from metal M (x gms) to metallic oxides MOn (x+n*16 gms).

Measurement of KLa in a bioreactor can be carried out by sodium sulfite oxidation method, that is, based on the oxidation of sodium sulfite to sodium sulfate in the presence of a catalyst (Cu++ or Co++). In a typical experiment, a laboratory fermenter was filled with 5 liter of 0.5 M sodium sulfite solution containing 0.003 M Cu++ ions and the air was sparged in. After 10 min, the air flow was stopped and a 10 mL sample was taken and titrated. The concentration of sodium sulfite in the sample was found to be 0.20 M. The oxygen uptake rate for this aerated system will work out to be

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.
