- Write the equilibrium constant expression, K, for the following reaction taking place in dilute aqueous solution.(CH3)3N (aq) + H2O(l) H(CH3)3N+ (aq) + OH-(aq)arrow_forwardConsider the following equilibrium reaction: 2 CH3OH + CH2O ⇌CH2(OCH3)2+ H2O ΔH = + 46 indicate the direction that the equilibrium will shift when the following changes are made.(No states are provided because the solvent for the reaction is not water, so aq for aqueous would not be appropriate.) (a)Concentration of CH3OH increases (b)H2O is removed from the reaction (c)Reaction is heatedarrow_forwardThe acetate ion, CH3COO–, reacts with water as a weak base: CH3COO–(aq) + H2O(l) ⇄ CH3COOH(aq) + OH–(aq), with K = 5.7 x 10-10 at 25°C.
