Answer:
The correct answer is B. A compound that is a hydrogen ion acceptor in an acid-base reaction
Answer:
C contains one N and three I atoms
Answer: The standard potential is -0.141 V
Explanation:
To calculate the Gibbs free energy for given value of equilibrium constant we use the relation:
where,
= standard Gibbs free energy = ?
R = Gas constant = 8.314 J/Kmol
T = temperature = 298 K
K = equilibrium constant =
Putting values in above equation, we get:
Also
where n = no of electrons gained or lost = 3
F = Faradays constant = 96500 C
= standard potential = ?
Thus the standard potential is -0.141 V
