Question

select the correct answer from each drop-down menu. in a reversible reaction, the forward reaction takes place simultaneously with the reverse reaction. such a reaction, on reaching equilibrium, will have a constant rate of forward reaction and reverse reaction, an equal number of products and reactants, similar masses of reactants and products

Explanation:

For the second dropdown in the reversible reaction equilibrium context: At chemical equilibrium, the rate of the forward reaction equals the rate of the reverse reaction (they are constant and equal). "An equal number of products and reactants" is incorrect as moles (not number of particles necessarily) can differ, and "similar masses of reactants and products" is also incorrect as masses depend on stoichiometry. So the correct option is "a constant rate of forward reaction and reverse reaction".

Answer:

a constant rate of forward reaction and reverse reaction
