Be sure to answer all parts. for each reaction, find the value of δso. report the value with the appropriate sign. (a) 3 no2(g) + h2o(l) → 2 hno3(l) + no(g) j/k (b) n2(g) + 3 f2(g) → 2 nf3(g) j/k (c) c6h12o6(s) + 6 o2(g) → 6 co2(g) + 6 h2o(g) j/k

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
