Hi! What order is the reaction between sodium thiosulphate and HCl with respect to the sodium thiosulphate (I think this is what I mean, we were changing the conc. of the sod.thio.)
Thanks! Tom

The equilibrium constant for 2NO2 <-----> N2O4 at 0,C is 58. The standard enthalpies of formation of NO2 is 33.18kJ/mol and N2O4 is 9.16kJ/mol.
a)Calculate the standard Gibbs free energy change at 0,C for the reaction
b)Calculate what fraction of a mixture of the two gases would be N2O4, at 100,C and a total pressure of 1 atm.
