ANS: The reversible reaction always attains equilibrium which proceeds both sides and never goes for completion. 2. The reaction CaCO3 ⇌ CaO +CO2(g) goes to completion in lime because: a) Of the high temperature. b) CaO is more stable than CaCO 3. c) CaO is not dissociated. The Haber process is a method to produce ammonia from hydrogen and nitrogen gasses. The reaction is. N 2 (g) + 3 H 2 (g) ↔ 2 NH 3 (g) If hydrogen gas is added after the reaction has reached equilibrium, the reaction will: a. shift to the right to produce more product. b. shift to the left to produce more reactants. c. stop. But the answer is 3.5x10^-4. Where have I gone wrong? 2. 1.68 moles of PCl5(g) was mixed with 0.36moles of PCl3(g) in a container of 2dm^3. 1.44 moles of PCl5 remained at equilibrium, calculate Kc (not Kp) giving units.

Why does ventriloquism work, and why can airliner flights make you feel disoriented? The answers to these and other questions about the human senses can be found. i) Kc = moldm -3 x (moldm-3) / (moldm-3) or ii) Kc = moldm -3 x moldm -3 x (moldm-3) / moldm -3 x (moldm-3) So there will be 1 more moldm -3 on the bottom of the Kc expression. And the units will. Calculations involving K c. In the equilibrium expression each figure within a square bracket represents the concentration in mol dm-3; The units of K c therefore depend on the form of the equilibrium expression; Some questions give the number of moles of each of the reactants and products at equilibrium together with the volume of the reaction mixture; The concentrations of.
