If the pressure of ` H_2` gas is increase from (1) atm to `100` atm. Keeping `H^+` concentration constatn at ` 1` M, the veltage of hydrogen half cell at `25^@ C` will be .

If the pressure of hydrogen gas is increased from 1 atm. To 100 atm, keeping the hydrogen ion concentration constant at 1 M, the reduction potential of the hydrogen half cell is at 25^(@)C will be

If the pressure of a gas at constant volume changes from 2 atm to 1 atm. The temperature changes from 0^@C

At constant temperature, the pressure of V mL of a dry gas was increased from 1 atm to 2 atm. The new volume will be :

At constant temperature, the pressure of VmL of a dry gas was increased from 1 atm to '2 ~atm .' The new volume will be

At constant temperature, the pressure of V mL of a dry gas was increased from 1 atm to 3 atm. The new volume will be :

At 27^(@) C it was observed in the hydrogenation of a reaction, the pressure of H_(2) (g) decreases from 10 atm to 2 atm in 10 min. Calculate the rate of reaction in M min^(-1)
