K= 1.44 at 1000 k for synthesis gas reaction:
CO(g)+H2O →←CO2(g)+H2(g)
if initially the gases are introduced into an empty vessel at a partial pressure at 1.0 ATM each, what will be the equilibrium partial pressure of each gas?
An ammonia gas-sensing electrode gave the following calibration points when all solutions contained 1 M NaOH. NH3 (M) E (mV) NH3 (M) E (mV) 1.00 105 268.0 5.00 104 368.0 5.00 105 310.0 1.00 103 386.4 1.00 104 326.8 5.00 103 427.6 A dry food sample weighing 312.4 mg was digested by the Kjeldahl procedure (Section 10-8) to convert all nitrogen into NH4 . The digestion solution was diluted to 1.00 L, and 20.0 mL were transferred KPot Na,H 36 to a 100-mL volumetric flask. The 20.0-mL aliquot was treated with 10.0 mL of 10.0 M NaOH plus enough NaI to complex the Hg catalyst from the digestion and diluted to 100.0 mL. When measured with the ammonia electrode, this solution gave a reading of 339.3 mV. Calculate the wt% nitrogen in the food sample.
