Arrange the bonds in order based on bond length. start with the longest bond, and end with the shortest bond.

c≡n
bond energy = 887 kj/mol
c=n
bond energy = 615 kj/mol
c–n
bond energy = 305 kj/mo

How does the value of the equilibrium constant show that a reaction reaches equilibrium very quickly? (a) the equilibrium constant is large. (b) the equilibrium constant is small. (c) the equilibrium constant is zero. (d) the value of the equilibrium constant does not show how quickly a reaction comes to equilibrium.
