Explanation :
1) always current should pass from anode to cathode in galvonic cell i.e left to right here.
2) Both electrodes and solution in same compartment should be same i.e Zn in Zn2+ solution and Ni in Ni2+ solution .
3) electrons should not flow from salt bridge
4) Ni having more reduction potential than Zn should be at cathode while Zn at anode , hence current from Zn to Ni
5) salt bridge ions should be opposite should be such that it balances charge in solution , i.e if more poistive charge is produced like zn2+ then Cl-
