a certain reaction is endothermic in the forward direction. the reaction has less moles of gas on the product side. which of the following stresses would increase the yield of the products (shift right)?

increasing the volume
decreasing the pressure
increasing the temperature
decreasing the reactant concentration

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.

the answer is true. hope it .
