Which of the reaction diagrams best shows a reaction with a change in enthalpy, ΔHrxn = -50 kJ/mol and an activation energy, Ea = 50. kJ/mol.

Using information from the previous problem and at the bottom of the page , identify  1) Do the electrons in the wire flow go to the right or to the left? 2) Over time, does the Zn electrode mass increase or decrease? 

Consider the information provided here and at the bottom of this page, including the reduction potential for the imaginary solid, Im(s).  Calculate the spontaneous voltage produced by this cell.  Im2+(aq) + 2e- à Im(s)                    E°1/2  =  – {E} V  Answer format:  Enter the value of the voltage using 2 sig figs in standard notation (not scientific).  Do not include units.

Fill in the blanks:  The cell potential, Ecell  =  Eocell  when _____________________ and,  Ecell  =  – (.0592/n) log Q  when ____________________________.

Going from room temperature, 298 K, to {T} K, the rate of a reaction doubles. Calculate the activation energy for the reaction in kJ/mol.  R = 8.314 x 10-3 kJ/mol Answer format:  Enter in standard notation, not scientific using 3 sig figs.  Do not include units.  

Refer to the list of reduction potentials provided, plus the additional reduction potential for the fake element, Fa provided here.  Calculate the value of E°cell. For the reaction,                  2AgNO3(aq) + Fa(s)  à 2Ag(s)+ Fa(NO3)2(aq)                              Fa2+(aq) + 2 e- à  Fa(s)       E°1/2 = – {E} V Answer format:  Enter your answer to 2 decimal places in standard notation. Do not include the units.
