Which statement correctly defines dynamic equilibrium?At dynamic equilibrium, the rates of forward and reverse reactions are equal. At dynamic equilibrium, the rate of the forward reaction is higher than the rate of the reverse reaction. At dynamic equilibrium, the forward and reverse reactions stop. At dynamic equilibrium, the concentrations of reactants and products are equal.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
