5.20 mol of solid A was placed in a sealed 1.00-L container and allowed to decompose into gaseous B and C. The concentration of B steadily increased until it reached 1.40 M, where it remained constant Then, the container volume was doubled and equilibrium was re-established. How many moles of A remain? Number mol A
Hydrogen and fluorine react to form hydrogen fluoride, like this: H2(9)+F2(9) 2 HF(G) The reaction is exothermic. Suppose a mixture of H2, F, and HF has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. perturbation change in composition shift in equilibrium to the right The temperature is...
Assume that the reaction for the formation of gaseous hydrogen fluoride (HF) from hydrogen (H2) and fluorine (F2) has an equilibrium constant K = [HF]2 / [H2][F2] of 1.15×10 2 at a certain temperature. In a particular experiment at this temperature 3.000 mol of each component were added to 1.500 mL flask. Calculate the equilibrium concentration of all species using an ICE table. Let x equal the number of moles per litre of H2 consumed to reach equilibrium.
Hydrogen iodide decomposes according to the reaction 2 HI(g) = H2(g) +1268) A sealed 1.50-L container initially holds 0.00623 mol of H2, 0.00414 mol of 12, and 0.0244 mol of HI at 703 K.
