Acetylene, C2H2, can be converted to ethane, C2H6, by a processknown as hydrogenation. The reaction is

C2H2(g)+2H2(g) <=> C2H6(g)

Given the following data, what is the value of Kp for thisreaction?

C2H2 (g)=209.2 KJ/mol

H2(g)=0 KJ/mol

C2H6(g)=-32.89 KJ/mol

The reversible chemical reaction

A+B <=> C+D

has the following equilibrium constant:

Kc=[C][D]/[A][B]=4.9

What is the final concentration of D atequilibrium if the initial concentrations are[A] = 1.00 M and[B] = 2.00 M?
