(d) What is the value of the activation energy of this reaction, expressed in kilojoules? i kJ/mol (e) What is the rate constant at 153.1°C?

Which of the following statements dealing with equilibria is incorrect? K, and K, are numerically equal if a reversible reaction involves only gases. At equilibrium in a reversible reaction, the rate of the forward reaction is equal to the rate of the reverse reaction. The vapor pressure of a liquid can be expressed as an equilibrium constant. Catalysts have no effect on the value of the equilibrium constant. We do not need to know the mechanism of a reaction to write an equilibrium constant expression.

When a reaction has k = 0.533 M–1 s–1 at 327 deg C, it is 2nd order of overall reaction.
