Homework Statement
OK. so i have a separation science lab report write up to do which involves the equilibrium of the tri-iodide ion dissociating into iodine and iodide. I know the concentrations at room temperature (which is very cold, about 10 degrees C, where i come from!), and thus the equilibrium constant. I then am asked to work out the equilibrium constant, K, at 25 degrees C. I know no other data, except a table of logK values for 0, 10, 20, 30, and 40 degrees C.
Homework Equations
equilibrium for I3-:
I2+I- <---> I3-
The Attempt at a Solution
I think you use the Van't Hoff equation, but i don't know the enthalpy...
Van't Hoff equation= Log(K1/K2) = enthalpy/R(1/T1-1/T2)
