Q:

The reduction potential of hydrogen half-cell will be negative if :
(1) $P (H_{2})$ = 2 atm and [H+] = 2.0 M
(2) $P (H_{2})$ = 1 atm and [H+] = 2.0 M
(3) $P (H_{2})$ = 1 atm and [H+] = 1.0 M
(4) $P (H_{2})$ = 2 atm and [H+] = 1.0 M

A) Option 1	B) Option 2
C) Option 3	D) Option 4

Answer & Explanation Answer: D) Option 4

Explanation:

$H^{+} - e^{-} \to \frac{1}{2} H_{2}$

Apply Nernst equation

$E = 0 - \frac{0.059}{1} \log (\frac{P H_{2}^{\frac{1}{2}}}{[H^{+}]})$

$E = - \frac{0.059}{1} \log (\frac{2^{\frac{1}{2}}}{1})$

Therefore E is Negative

Q:

According to John Maynard Keynes, employment depends upon

A) aggregate demand	B) aggregate supply
C) effective demand	D) rate of interest

Answer & Explanation Answer: C) effective demand

Explanation:

J.M Keynes’ theory of employment is a demand-deficient theory. This means that Keynes visualised employment from the demand side of the model. His theory is a demand-oriented approach, as opposed to the classical supply side model.

According to him,the volume of employment in a country depends on the level of effective demand of people for goods and services. Thus, unemployment is attributed to the deficiency of effective demand.
