Giving 98 points which statement about enthalpy is true? a.)the enthalpy of formation for a pure element in its standard state is always positive. b.)the enthalpy of formation for a pure element in its standard state is always negative. c.)enthalpy is a state function because its change depends only on initial and final conditions. d.)enthalpy is not a state function because its change depends on the identities of the reactants and products.

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
