What is the standard reduction potential, E, for the half-reaction Al3+ (aq)
olchik [2.2K]

Answer:

E° = -1.66 V

Explanation:

The standard reduction potential is also known as the standard electrode potentials and it tries to find the probability that an element will be reduced or undergo reduction.

From activation series online showing the standard reduction potentials for half cells, the standard reduction potential of Al3+ (aq) + 3e- -> Al(s) is;

E° = -1.66 V

Consider the following reversible reaction. What is the equilibrium constant expression for the given system?
ladessa [460]
The question is incomplete. Complete question is attached below
..........................................................................................................................

Answer: 
Equilibrium constant (K) is defined as the ratio of concentration of product to concentration of reactant.

For the reaction:  2H2O(g)    ↔     2H2(g)      +       O2(g)

Equlibrium constant = \frac{[H_2]^2[O_2]}{[H_20]^2}

[ ] bracket in above expression indicates concentration.
