Question

B. Consider the system N2 (9) 3H2 (g) 2 NHs (9) dbie of NHs was placed in a 2.000 liter flask at 25°C. When equilibrium at that temperature, it was determined that the ammonia was reduced A 2.568-g sample was reached N to 75.0% of its original value. 1. Calculate K for the decomposition of 2.00 moles of ammonia at 25.0°C. 2. Calculate K for the decomposition of 2.00 moles of ammonia at NH3 is -46.1 kJ/mol) C. For the system PCls (g) PCl3 (g) Cl2 (g) K is 1.0 at a certain temperature. If one starts wi 1. In what direction will the reaction proceed? th 0.50 atm of both PCh and Cl2 (g) 2. What are the partial pressures of all species when equilibrium is reached? 3. If after equilibrium is reached, the partial pressure of chlorine gas is reduced to 0.2 atm, what are the partial pressures of all species when equilibrium is re- established? When stress is imposed on the system, does the system fully recover from that stress (i.e., Are the equilibrium pressures the same before and after the stress?)? 4.

please show all work

thanks
