Which shows the correct relationship? A.) Eo cell > 0 = nonspontaneous reaction B.) Eo cell > 0 = spontaneous reaction C.) Eo cell = 0 = nonspontaneous reaction D.) Eo cell Answer: B.) > 0 = spontaneous reactionExplanation:The standard emf of a cell is related to Gibbs free energy by following relation: = gibbs free energyn= no of electrons gained or lostF= faraday’s constant = standard emfwhen = +ve, reaction is non spontaneous= -ve, reaction is spontaneous= 0, reaction is in equilibriumThus reaction is spontaneous when = +veThus reaction is non spontaneous when = -veThus reaction is in equilibrium when = 0.
Answer : The mass of produced will be, 6.16 grams. Explanation : Given, Mass of = 14 g Mass of = 56.70 g Molar mass of = 100 g/mole Molar mass of = 36.5 g/mole Molar mass of = 44 g/mole First we have to calculate the moles of and . Now we have to
