Web45K subscribers in the alevel community. This is a place to discuss anything related to IAL, AS and A2. We welcome all students! WebThe 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 direction of the reaction that is taking place.

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. WebBy Grade Level. Middle School.
