What is Keq at 25°C of the spontaneous cell made from the Zn²⁺/Zn (-0.76 V) and Br₂/2Br- (1.07 V) half cells?

The cell potential (E°cell) is calculated by subtracting the anode potential from the cathode potential: E°cell = 1.07 V - (-0.76 V) = 1.83 V. Using the Nernst equation at standard conditions, Keq = 10^(nE°cell/0.0592), where n is the number of electrons transferred (2 in this case). Thus, Keq = 10^(2*1.83/0.0592) ≈ 10^61.
