A) \[{{E}_{cell}}\] and \[{{\Delta }_{r}}G\] of cell reaction both are extensive properties.
B) \[{{E}_{cell}}\] and \[{{\Delta }_{r}}G\] of cell reaction both are intensive properties.
C) \[{{E}_{cell}}\] in the intensive property while \[{{\Delta }_{r}}G\] of cell reaction is an extensive property.
D) \[{{E}_{cell}}\] is an extensive property while \[{{\Delta }_{r}}G\] of cell reaction is an intensive property.
Correct Answer: C
Solution :
\[{{E}_{cell}}\] is intensive while \[{{\Delta }_{r}}G\] is extensive. (In the relation,\[\Delta G=-n\,FE,\]\[E\]depends only on nature of the cell reaction so it is intensive whereas value of \[\Delta G\]depends upon the value of n. So it is extensive.
