Effect of Concentration on emf

Post  little s on Wed Nov 26, 2008 3:15 am

Predict the cell potential for the following reaction when the pressure of oxygen is 2.50 atm, the hydrogen ion concentration is 0.14M and the bromide concentration is 0.37M.

the reaction is...
O2 + 4H+ + 4Br- ---> 2H2O + 2Br2 E°= 0.152V

i know you use the nernst equation to solve this but i cant seem to get the right answer for some reason. =S

thanks for your help!
