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.  

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? 

Suppose a Voltaic/Galvanic cell at 298 K runs on the reaction,  Sn(s) + Nr2+(aq)   à  Sn2+(aq) +   Nr(s), where Nr is a fake element with the reduction potential,    Nr2+(aq) + 2e- à Nr(s)         E°1/2 = 0.40 V.  The cell contains the following concentrations in each half cell: Sn(s) /Sn2+, [Sn(NO3)2] = 0.70 M               Nr(s)/Nr2+, [Nr(NO3)2] =  {M} M      What is the value of Ecell?            Answer format:  Enter the answer in Volts but do not include the units.  Enter 2 sig figs in standard, not scientific notation. 

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.

What mass of silver metal (molar mass = 107.87 g/mol) will be formed by passing {I} A through AgNO3(aq) for {t} seconds?  Answer format:  Enter your answer in grams but do not include the units.  Enter 2 sig figs in standard, not scientific notation.

A concentration cell consists of two Zn/Zn2+ electrodes. The electrolyte in side A is {M} M Zn(NO3)2 and in side B is 0.10 M Zn(NO3)2. What is the voltage of the cell at 25°C for this cell running spontaneously?  Answer format:  Enter the answer in standard, not scientific notation using 3 decimal places.  Do not include units.
