Salt bridge A concentration cell similar to the one shown is composed of two Zn electrodes and solutions of different Zn2+
concentrations. The left compartment contains 1.42 M Zn2+, and the right compartment contains 0.574 M Zn2+.
Calculate the cell potential for this reaction at 298 K.
volts
In this zinc concentration cell, the reaction would proceed spontaneously(left to right, right to left)

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

what is the question?

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
