Consider the equilibrium system described by the chemical reaction below, which has a value of Kc equal to 1.87 × 10⁻³ at a certain temperature. If 5.00 g of solid PH₃BCl₃ and 0.0700 g of BCl₃ are added to a 4.500 L reaction vessel, what will the equilibrium concentration of PH₃ be? PH₃BCl₃(s) ⇌ PH₃(g) + BCl₃(g) 1.) Set up the expression for Qc and then evaluate it to determine the direction of the reaction. Do not combine or simplify terms 2.) Based on the given values and your value for Qc, set up ICE table in order to determine the unknown. 3.) Based on your ICE table, set up the expression foe Kc in order to determine the unknown. 4.) Based on your ICE table and expression for Kc, solve for the partial pressure of PH3, at equilibrium.

Hydrogen peroxide has several advantages and disadvantages as a potential chemical for pharmaceutical industry and cosmetic industry. 2 H2O2 (g) 2H20 (g) + O2 (g) K eq = 7.3 X 10 -5 If 0.5mol of H2O2 (g) was placed in a 2.0L flask, what is the equilibrium concentration of water vapour, oxygen and hydrogen peroxide at 800°C? If you make any assumption, you need to check it for validity.
