Gold catalyzes the decomposition of hydrogen iodide into its elements according to the equation: 2HI (g) 2(g) + H2(g). Consider the illustration at the right. What type of catalyst would this be: heterogeneous or homogeneous? ive a reason for your choice.
Homework Answers
Ans :
Keq is given as :
Keq = [HI]2 / [H2] [I2]
putting values :
= (0.55)2 / (0.15) (0.033)
= 61.1
Ans : Heterogenous
A heterogenous catalyst is the one that is in a different state with respect to reactants. The gold catalyst is solid , whereas the reactants are gaseous , so it is a heterogenous catalyst.
