Consider the equilibrium Na2O(s) + SO2(g) <----->(actually 2 arrows facing opposite direction) Na2SO3(s). (a) Write the equilibrium constant-expression for this reaction in terms of partial pressures. (b) Why doesn't the concentration of Na2O appear in the equilibrium-constant expression?
When operational in the determination of the calorimeter constant, a DC power source reads 3.60 volts and 2.65A. The resulting thermogram has a slope of 0.0438 degrees C/
