I Review I Constar Learning Goal: To learn how to use the Nernst equation. Part A The standard reduction potentials listed in any reference table are only valid at the common reference temperature of 25 °C and standard conditions of 1 M for solutions and 1 atmn for gases. To calculate the cell potential at nonstandard conditions, one uses the Nernst equation, What is the value for the reaction quotient, Q, for the cell? Express your answer numerically. • View Available Hint(s) E = E° – 2.303 RT log10 nF Q = 0.103 where E is the potential in volts, E° is the standard potential in volts, R=8.314 J/(K- mol) is the gas constant, T is the temperature in kelvins, n is the number of moles of electrons transferred, F = 96, 500 C/(mol e) is the Faraday constant, and Q is the reaction quotient. Submit Previous Answers v Correct At the common reference temperture of 298 K, substituting each constant into the equation the result is Part B What is the value for the temperature, T, in kelvins?
