The equilibrium constant (K_{c}) for the reaction
2HCl(g) \rightleftharpoons H_{2}(g) + C*l_{2}(g)
A
is 4.17 * 10^{- 34} at 25 deg C What is the equilibrium constant for the reverse reaction at the same temperature? Round your answer to 3 significant digits.
H 2 (g)+Cl 2 (g) \rightleftharpoons 2HCl(g)

K_c' =
