Question

question 1
the ice table for a reaction contains information about...
...the amount of ice needed to stabilize the reaction.
...the temperature and rate of the reaction.
...the initial, change, and equilibrium concentrations of the molecules.
...the initial chemical energy required for the reaction.
question 2
to calculate kc, its essential to know...
only the initial concentrations of reactants.
only the final concentrations of products.
the equilibrium concentrations of all reactants and products.
the temperature at which the reaction takes place.

Explanation:

For Question 1, an ICE table stands for Initial - Change - Equilibrium and lists the initial, change, and equilibrium concentrations of molecules in a reaction. For Question 2, the equilibrium constant $K_c$ is calculated using the equilibrium concentrations of all reactants and products based on the law of mass - action.

Answer:

Question 1: the initial, change, and equilibrium concentrations of the molecules.
Question 2: the equilibrium concentrations of all reactants and products.
