for the reaction 2HBr2 = H2 + Br2 K=2.00x10^-19 at 298K what can be said about this reaction to completion at 1200 The reaction goes to completion at 1200 K Item 3 O The equilibrium lies far to the right at room temperature. For a reaction Submit Hints My Answers Give Up Review Part the equilbrium constant K is defined as the ratio of products to reactants at equilibrium: Correct Because K represents the ratio of products to reactants, the magnitude of K is an indicator of the Part C levels of products and reactants present when the For the reaction reaction is at equilibrium. Some chemical reactions 2HBr(g) H2(g) Br2(g), K-2.00 x 10 19 at 298 K proceed almost fully to product, whereas other chemicals hardly react with each other at all, or what can be said about this reaction at this temperature? react so as to have significant amounts of both reactants and products at equilbrium. O The equilibrium lies far to the right O The reaction will proceed very slowly. O The reaction contains significant amounts of products and reactants at equilibrium. O The equilibrium lies far to the left. Submit Hints My Answers Give Up Review PartExplanation / Answer
Solution. Equalibrium constant k is an indicator of the levels of products and reactants present, when the reaction is at equalibrium,
The above reaction is indicate "The reaction contains significant amount of products and reactants at equilibrium".
