Solution: Suggest four ways in which the concentration of hydrazine, N2H4, could be increased in an equilibrium described by the following equation:N2(g) + 2H2(g) ⇌ N2H4(g)                      ΔH = 95 kJ

Solution: Suggest four ways in which the concentration of hydrazine, N2H4, could be increased in an equilibrium described by the following equation:N2(g) + 2H2(g) ⇌ N2H4(g)                      ΔH = 95 kJ

Problem

Suggest four ways in which the concentration of hydrazine, N2H4, could be increased in an equilibrium described by the following equation:
N2(g) + 2H2(g) ⇌ N2H4(g)                      ΔH = 95 kJ

Solution
  • There are several ways to make an equilibrium favor one side. We can change the conditions, concentration etc depending on the phases of reactants and products, enthalpy etc .
  • A possible way to increase the concentration of the product  N2H4(g) is to tweak the temperature of the reaction. A positive ΔH suggests that it the reaction is endothermic (heat absorbing). An INCREASE in TEMPERATURE will FAVOR FORMATION of PRODUCT for endothermic reactions.
