Catalytic decomposition of ammonia (NH3) in the gas phase follows the reaction: 2NH3---> N2 + 3H2
Catalytic decomposition of ammonia (NH_3) in the gas phase follows the reaction: 2NH_3 rightarrow N_2 + 3H_2 The experiments showed that the half-life of the reaction depends on the initial pressure of ammonia as follows: Pressure (mmHg) 65 105 150 185 t_1/2 (s) 290 460 670 820 What is the reaction order and the value of the rate constant? 3: 1 mole ratio of hydrogen: nitrogen gas mixture flows through a catalytic converter at 400. degree C. The mixture coming out of the converter was observed to contain 3.03 atm of NH_3 gas and the total pressure was 30.00 atm. Assuming that chemical equilibrium is established inside the converter, calculate the equilibrium constants K_p and K_c for the reaction: 3/2 H_2(g) + 1/2 N_2 (g) NH_3(g) Consider 100. mL of aqueous NaOH solution that has pH 10 at room temperature. a) What would be the pH if you added 5.00 mg of Ca(OH)_2 to the solution? b) What would be the pH if you added 2.00 g of Ca(OH)_2 to the solution? c) What would be the pH if you added 10.0 mL of 5.00 M HC1 to the solution? d) What would be the pH if you dissolved 10.0 mg of NaCl into the solution? The molar mass of Ca(OH)_2 is 74.09 g/mol and the solubility constant K_sp = 4.7 times 10^-6. The molar masses for HC1 and NaCl are 36.46 g/mol and 58.44 g/mol, respectively.
