A lawyer following the pure legal advocate concept will inevitably fall short of being a(n) ___________ person.

For the burning of a liquid fossil fuel the values of thermodynamic functions will be:  

The van’t Hoff Equation is a mathematical relationship relating the equilibrium constant to the temperature of the system: lnKeq=-∆Horeaction/R(1/T) +∆Soreaction/R Where ΔHoreaction and ΔSoreaction are correspondently standard enthalpy and entropy changes of reaction and R is the universal gas constant (8.314 J mol-1k-1).  The graphical interpretation of van’t Hoff Equation in form of the plot of lnKeq vs 1/T gives you an opportunity to determine both thermodynamic functions from the value of the equilibrium constant: the slope of this plot is equal to -ΔHoreaction/R and y-intercept – to ΔSoreaction/R.  Note that your values will come in Joules and the temperature for all thermodynamics calculations should be converted to Kelvins. The student explored the famous Haber process: N2(g) + 3H2(g)  => 2NH3(g), and obtained the following data for the equilibrium constant: Temperature, oC Equilibrium constant 25.00 3.86E+05 75.00 2.27E+03 125.0 4.04E+01 175.0 1.52E+00 225.0 8.37E-02 Assignment and Rubric: Use your Lab Report Template to answer the questions below.
