neutron

stanfordream...if im not mistaken..this is how u would find the new Keq at 40C
(btw..in the original problem i meant to write standard state, not STP)

dG= -RT ln Keq
dG= dH - TdS

dH - TdS = -RT ln Keq

-DH/RT - DS/R = ln Keq

now u would find the dH and dS values for the rxn, plug those in, along with R and the new temperature and find Keq at 40C!!!!!
