What happens to the voltage when the salt bridge is removed from the two half cells and why?

One Line Answer

The voltage drops to zero, as the current will stop flowing in the circuit of the cell.

A Galvanic cell converts _______ energy into _______ energy.

Arrange Ag, Cr and Hg metals in the increasing order of reducing power. Given:

`(E_(Ag^+)^o)/(Ag) = +0.80V`

`(E_(Cr^(+3))^o)/(Cr) = -0.74V`

`(E_(Hg^(+2))^o)/(Hg) = +0.79V`

Which one of the following statements is true for the galvanic cell?

The emf \[\ce{E^\circ_\text{cell}}\] of the following reaction is 0.89 V.

\[\ce{3Sn^{4+} + 2Cr -> 3Sn^{2+} + 2Cr^{1+}}\]

Calculate the value of ΔG° for the reaction. Predict whether the above reaction will be spontaneous or not.
