It helps compare wavelengths of light. This means it helps determine which side of the spectrum (visible or not).
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
The answer is Coal. Atmospheric pollution is least when geothermal electricity is used to produce electricity.
Answer:
The positively charged particle will go towards the negatively charged particle because opposites attract.
