Answer of last question 1:17:02 : 1) ZnSO⁴ + Cu -------. × (Not possible ) _ because Cu cannot Displace Zn from ZnSO⁴. So , Here oxidation of Copper is not possible , that is why Copper vessel is not melt and we can keep easily ZnSO4 Solution in Copper vessel OR. 2) Let Assume, Copper is oxidised(Anode Formation) - Cu --- Cu²+ + 2e And Zinc is reduced (Cathode Formation) - Zn²+ +2e --- Zn Now, E . Standard Reduction potential of Anode (Copper) Cell = 0.34V &. E_ Standard Reduction Potential of Zn = -0.76V NOW , E°MF of cell = E° (Cathode_ReductionPotential) - E° (Anode_ReductionPotential) = -0.76V - 0.34 = -1.1 V Here, E°MF of cell is negative , So gibbs free energy will be +ve and hence Process will be Non - Spontaneous !!! So , Our assumption is Wrong & hence we can keep ZnSO4 in Cu vessel .....

Yes me too i was confused about this how it become 2.0V instead of 1.6V as (SRP= -SOP) and the chemical equation was already (oxidation state) so it need to be converted in positive, and after that by applying the formuala of (Eright -Eleft) it will be ( +1.8 - +0.2)V = (1.6V) Answer

33:00 : confusion solve👇 Hey guys, sir has taken OP =-0.2v and sir has written the 1st formula at 32:25[EMF of cell = Eop(anode)+ ERP(cathode)] if you put the values Eop(anode)=-2v and Erp(cathode)=+1.8v in the first formula that is written by sir at 32:25 then the EMF of cell would come out to be 1.6v but sir has said EMF of cell=2v at 32:00 So, I think sir has taken a wrong arbitrary example of taking OP=-0.2v at 30:20 cuz all the 5 formulas that is written by sir from 32:18 to 35:12 are correct I verified it using the example of Zn(op)=+0.76v and Cu(rp)=+0.34 you can check by yourself by taking some example values from book or Google, none of the formulas are wrong, the MISTAKE is that there should be OP=+0.2v of the arbitrary example.
