Homework Answers
When bonds are broken energy is required , therefore enthalpy is positive.
When bonds are formed energy is released, therefore enthalpy is negative
Enthalpy of reaction = Sum of both these enthalpies
Endothermic reaction means a positive value of enthalpy of reaction which indicates that the energy released when forming the bonds is lesser than the energy required in breaking these bonds.
Hence option a is correct

The pollutant NO is formed in diesel engines. The reaction fixes atmospheric nitrogen with oxygen to form NO. The reaction is: N2(g) + O2(g) = 2NO(g). If the equilibrium constant for this reaction at elevated temperatures is 5.60E-11, then what is the partial pressure of NO gas if nitrogen is 1.50 atm and oxygen is 0.500 atm? The units are atmospheres.
