Question

Consider the following reaction

N2(g) + 3H2(g)  ⇌  2NH3(g)              ΔH°rxn = –92 kJ

Which one of the following statements about this reaction is correct?

  •  
    A. 

    A plot of ln K vs. (1/T) will be a straight line with a negative slope.

  •  
    B. 

    Compression of the system will shift the equilibrium to the left.

  •  
    C. 

    ½ ΔH°rxn is equal to the standard enthalpy of formation of NH3(g).

  •  
    D. 

    An increase in temperature will shift the equilibrium to the right.

  •  
    E. 

    Addition of N2(g) at constant temperature will increase the equilibrium constant.
