Answer:
Both reactivity and electronegativity decrease down a group.
I'm assuming this is multiple choice...
Explanation:
I believe the answer is b.
C. Come to a complete stop begin the stop line
The concentrations of the species at equilibrium is obtained from the ICE table.
<h3>What is equilibrium constant?</h3>
The equilibrium constant shows the extent to which a reactant has been converted into products. A large equilibrium constant means that most of the reactants are converted into products The question is incomplete as the details as missing.
However, for a hypothethical reaction; nA + mB ⇄ xC + zD, the equilibrium constant is obtained from; K = [C]^x [D]^z/[A]^n [B]^m. The concentrations of the species at equilibrium is obtained from the ICE table.
