Initially, only AA and BB are present, each at 2.00 MM. What is the final concentration of AA once equilibrium is reached

Explanation:

Hello.

In this case, for the chemical reaction at equilibrium:

The equilibrium expression is:

Which in terms of the ICE methodology can be written as:

Solving for , we obtain:

It means that the concentration of A once equilibrium is reached turns out:

Best regards.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

it's all four options.
