Question

Learning Goal To learn how to use the Nernst equation 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 atm for gases To calculate the cell potential at nonstandard conditions one uses the Nernst equation 2 303 RT nF E E log10 Q where E is the potential in volts E is the standard potential at 25 C 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 is the reaction quotient At the common reference temperture of 298 K substituting each constant into the equation the result is E E 0 0592 Vlog10 n at 55 C where Fe2 2 90 M and Mg2 0 310 M Part A What is the value for the reaction quotient Q for the cell Express your answer numerically View Available Hint s Q Submit Part B VAE What is the value for the temperature T in kelvins Express your answer to three significant figures and include the appropriate units View Available Hint s
