Be sure to answer all parts. kc for the reaction of hydrogen and iodine to produce hydrogen iodide, h2(g) + i2(g) ⇌ 2hi(g) is 54.3 at 430°c. determine the initial and equilibrium concentration of hi if initial concentrations of h2 and i2 are both 0.11 m and their equilibrium concentrations are both 0.045 m at 430°c. [hi]i = m [hi]e = m

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
