Question

What mass of reactants are used during the reaction hydrogen bromine = hydrogen bromide

Answer 1

The mass of reactants used in the reaction can be calculated based on the stoichiometry of the reaction and the given information about the concentration of bromine gas at equilibrium.

Step-by-step explanation:

The mass of reactants used in the reaction hydrogen + bromine = hydrogen bromide can be calculated using the stoichiometry of the reaction and the given information about the concentration of bromine gas at equilibrium. Since the mole ratio of hydrogen to bromine is 1:1, the concentration of hydrogen gas at equilibrium is also 0.00243 M. The concentration of hydrogen bromide at equilibrium can be determined by rearranging the equilibrium expression.

Answer 2

The mass of reactants used during the reaction hydrogen bromine = hydrogen bromide is not provided in the given information. We only have the concentration of bromine gas at equilibrium.

Step-by-step explanation:

The reaction is:
H₂ + Br₂ → 2HBr

Since the reaction begins with only HBr and the mole ratio of H₂ to Br₂ is 1:1, the concentration of H₂ at equilibrium is also 0.00243 M. The equilibrium expression can be rearranged to solve for the concentration of HBr at equilibrium.

Therefore, the mass of the reactants used during the reaction is not provided in the given information. We only have the concentration of bromine gas at equilibrium.
