Q

Equilibrium Law

A

The concentration of products to the power of their coefficients, divided by the concentration of the reactants to the power of their coefficients is equal to the equilibrium constant

17
Q

Reaction Quotient

A

Provides an understanding of amount of products and reactants before equilibrium is reached

18
Q

Equilibrium Constant

A

Ratio of reactants to products in a reaction when it is at equilibrium

19
Q

Kc>10^4

A

Significantly more product than reactant
