alleryThe quantity used to predict the direction a reaction will take is the:
AReaction quantum
BReaction quantity
CReaction quandary
DReaction quotient
Answer & Solution
Correct answer: D. Reaction quotient
1. The equilibrium constant alone does not say which way a mixture will move.
2. For this purpose we calculate the reaction quotient Q.
3. So the correct answer is reaction quotient.
