The emf of a cell corresponding to the following reaction is 0.0199 V at 298 K. `Zn(s) + 2H^(+)(aq) rightarrow Zn^(2+)(0.1M) + H

The emf of a cell corresponding to the following reaction is 0.0199 V at 298 K.
`Zn(s) + 2H^(+)(aq) rightarrow Zn^(2+)(0.1M) + H_(2)(g)(E_(Zn//Zn^(2+))^(@) = 0.76V`

A. 8
B. 9
C. 10
D. 11
