Reaction quotient a level chemistry
WebJan 30, 2024 · The reaction quotient aids in figuring out which direction a reaction is likely to proceed, given either the pressures or the concentrations of the reactants and the products. The Q value can be compared to the Equilibrium Constant, K, to determine the … WebThe reaction quotient, , is calculated the same way as equilibrium constant; however, the concentrations used are derived from a nonequilbrium state. Consider the reaction below. If this reaction is NOT in equilibrium, then the reaction quotient is defined as If it’s at equilibrium then equilibrium constant is defined as

WebJan 26, 2024 · The reaction may be said to be "complete" or "quantitative." If the value for the equilibrium constant is small, then the equilibrium favors the reaction to the left, and there are more reactants than products. If the value of K c approaches zero, the reaction may be considered not to occur. WebAt equilibrium, the value of the equilibrium constant is equal to the value of the reaction quotient. At equilibrium, (2.3.7) K e q = Q c = [ N 2 O 4] [ NO 2] 2 = 0.042 0.016 2 = 1.6 × 10 2. The equilibrium constant is 1.6 × 10 2. Note that dimensional analysis would suggest the unit for this K e q value should be M−1.
