Question

hoe to calculate EMF. of a reaction..​

Answer 1

Answer:

Sample EMF Calculation

Mg(s) + 2 H+(aq) → Mg2+(aq) + H2(g) a) Calculate the cell EMF for the reaction. b) Identify if the reaction is galvanic.

Solution: Step 1: Break the redox reaction into reduction and oxidation half-reactions. ...

Answer: The cell EMF of the reaction is +2.372 Volts and is galvanic.

Answer 2

$\huge\star\mathfrak\red{{Answer:-}}$

Sample EMF calculation:

Step 1: Break the redox reaction into reduction and oxidation half-reactions.

Step 2: Find the standard reduction potentials for the half-reactions.

Reversed reaction:

Step 3: Add the two E0 together to find the total cell EMF, E0cell

Step 4: Determine if the reaction is galvanic.
