<h3>What is a redox reaction?</h3>
We define a redox reaction as one in which a specie is oxidized and another is reduced.
Now;
Eo cell = cell potential = -0.13 V - (+0.34 V) = -0.47 V
n =number of moles of electrons = 2 mole of electrons
K = equilibrium constant
ΔG = change in free energy
Eo cell = 0.0592/n log K
-0.47 = 0.0592/2 log K
log K = -0.47 * 2/0.0592
K = 1.3 * 10^-16
ΔG = -nFEo cell
ΔG = -(2 * 96500 * -0.47)
ΔG = 90.7kJ

Answer:</h3>
#1. Type of reaction: Single displacement
#2. Balanced equation: Zn + 2HCI → ZnCI₂ + H₂
<h3>
Explanation:</h3>
<u>We are given;</u>
- The equation; Zn+HCI → ZnCI₂ + H₂
Assuming we are required to identify the type of reaction and balance it;
- The reaction is a <u>single displacement reaction.</u>
- Zinc metal displaces hydrogen atom from hydrochloric acid to form a salt, zinc chloride and hydrogen gas.
- To balance the equation, we put coefficients on the reactants and products for the number of atoms of each element to be equal on both sides of the equation.
- In this case, the appropriate coefficients are 1, 2, 1 and 1
- Therefore, the balanced equation will be;
Zn + 2HCI → ZnCI₂ + H₂
