Question

if the pressure of hydrogen gas is increased from 1atm to 100 atm. Keeping the hydrogen ion conc constant at 1 M the voltage of hydrogen half cell at 25°C will be 
a)0.059 V
b)0.0295 V
c)0.59 V
d)0.118 V

Answer 1

hii friend...

a ) 0.059

Answer 2

When keeping the Hydrogen at constant level, the M can be calculated and includes hydrogen half cell.

It is evaluated in bringing forth hydrogen half cell that includes rich content and taken with concentration constant of 1M.

It must be attached with voltage and carry out at 250C will be 0.59V.
