The standard emf for the cell using the overall cell reaction below is +2.20 v: 2al(s) + 3i2 (s) → 2al3+ (aq) + 6i− (aq) the emf generated by the cell when [al3+] = 5.0 ⋅ 10−3 m and [i−] = 0.10 m is v. the standard emf for the cell using the overall cell reaction below is +2.20 v: (s) + (s) (aq) + (aq) the emf generated by the cell when [] = 5.0 m and [] = 0.10 m is v. 2.20 2.41 2.10 2.30 2.23

+2.10V

Explanation:

Using Nernst equation :

where,

= standard emf for the cell = +2.20 V

n = number of electrons in oxidation-reduction reaction = 6

= emf of the cell = ?

 = concentration =

 = concentration =

Now put all the given values in the above equation, we get:

The standard emf for the cell using the overall cell reaction below is +2.10 V

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
