Multiplying every stoichiometric coefficient in an equation by a factor changes K:
AInversely to that factor
BExponentially by that factor
CLinearly by that factor
DNot at all in any way
Answer & Solution
Correct answer: B. Exponentially by that factor
1. The equilibrium constant is a product of concentration terms raised to the coefficients.
2. Scaling the coefficients therefore scales the exponents.
3. Changing the stoichiometric coefficients in an equation by some factor results in an exponential change in the equilibrium constant by that same factor.
4. Doubling every coefficient squares the constant rather than doubling it.
