Answer» Correct Answer - `a. 289500C` ,`b.193000C` , `c. 482500C`. `a.` `Al^(3+)+3e^(-) rarr Al` `1 mol of Al=3F` `=3xx96500` `=289500C` `b.` `Cu^(2+) +2e^(-) rarr Cu` `1 mol of Cu=2F` `=2xx06500` `=193000C` `c.` `MnO_(4)^(c-)+5e^(-) rarr Mn^(2+)` `1 mol of MnO_(4)^(c-)=5F` `=5xx96500C` `=482500C` |
