Webb5 maj 2024 · So that makes the change in BrF as +2 x (You use the reaction coefficients to know that). Those are the "C" column (for "change") . Finally, write your "E" column amounts: the initial (I) plus the change (C) amounts, for each of the three gases. So now, using those E amounts, set up your equilibrium expression: K = [BrF]^2 / ( [ F 2 ] [ Br 2 ... WebbBalance this redox reaction by using the half reaction method. O2− + F2 → O2 + F−. Answer. 2O 2− + 2F 2 → O 2 + 4F −. Many redox reactions occur in aqueous solution—in water. Because of this, in many cases H 2 O or a fragment of an H 2 O molecule (H + or OH −, in particular) can participate in the redox reaction.

WebbC. R ↔ P + energy represents an exothermic reaction. Only changing temperature could change a keq. To decrease keq, the concentration of reactants must increase and the concentration of products must decrease and concentration of reactants must increase…As this is an exothermic reaction, when temperature is increased, it will cause … Webb7 juli 2010 · Mark Scheme (Results) June 2010 GCE GCE Chemistry (6CH05/01) Edexcel Limited.
