Using standard electrode potentials calculate ΔG∘rxn and use itsvalue to estimate the equilibrium constant for each of thereactions at 25 ∘C.
A. Cu2+(aq)+Zn(s)→Cu(s)+Zn2+(aq)
B. Br2(l)+2Cl−(aq)→2Br−(aq)+Cl2(g)
C. MnO2(s)+4H+(aq)+Cu(s)→Mn2+(aq)+2H2O(l)+Cu2+(aq)
Find K. All answers must have one significant figure. Pleaseshow all your work and equations used. Thank you!!
