WebApr 13, 2024 · a level chemistry reaction preference question. It seems like the mark scheme is talking about reaction 2 being irreversible. This would mean that all the reactants would be used up to form as much product possible. In a reversible reaction like reaction 1 however, some of the reactants will not get used up as there will be equal rates of the ... WebThe reaction quotient, Q, is a measure of the relative amounts of reactants and products during a chemical reaction at a given point in time. By comparing the value of Q to the equilibrium constant, K eq, for the reaction, we can determine whether the forward reaction or reverse reaction will be favored. Take the following generic equation: aA ...
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.
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.
