Van't Hoff Equation Jacobus van't Hoff received the first Nobel Prize in Chemistry (1901) for his fundamental discoveries in physical chemistry. (a) Write the van't Hoff equation listed on pg. 760: (b) Write the balanced equation for the synthesis of dinitrogen tetroxide gas from nitrogen dioxide: (c) If the equilibrium constants for the reaction in part (b) are: @0 degree C, K_c = 6.9 times 10^-4 M @ 600 K, K_c = 4.6 times 10^2 M what is the Delta H degree_rxn for his reaction? (d) Write the balanced equation for the reaction of nitrogen with oxygen to produce nitrogen monoxide:

Explanation / Answer

b) 2NO2(g) <===> N2O4(g)

c) ln(k2/k1) = DHrxn/R[1/T1-1/T2]

   ln(4.6*10^-2/(6.9*10^-4)) = x/8.314((1/273)-(1/600))

x = DHrxn = 17.49 kj/mol

d) N2(g) +O2(g) ---> 2NO(g)
