Question

2.) The following reaction happens in an acidic solution. How many electrons are transferred when the equation is balanced?

Fe2+ + MnO4- ---> Mn2+ + Fe3+

The reaction A + B ? ? + D has the free energy reaction coordinate diagram shown below. Using this diagram, which of the following statements true? Reaction Coordinate O a. The reaction is nonspontaneous O b.The reaction essentially goes to completion. o c Keq for the reaction is greater than 1 od. The entropy of the system increases during the reaction.

Explanation / Answer

1) here delta G < 0 that is delta G is negative. hence reaction is spontaneous.

delta G = -RTln Keq

option b and C are true statements.

2) 5 Fe2+ + MnO4- + 8 H+........................> 5 Fe3++ Mn2++ 4 H2O

five (5) electrons are transferred.
