The equilibrium constant of a system, K, can be related to the standard free energy change, ΔG∘, using the following equation: ΔG∘=−RTlnK where T is a specified temperature in kelvins (usually 298 K) and R is equal to 8.314 J/(K⋅mol)Acetylene, C2H2, can be converted to ethane, C2H6, by a process known as hydrogenation. The reaction is C2H2(g)+2H2(g)⇌C2H6(g) Given the following data at standard conditions (all pressures equal to 1 atm and the common reference temperature 298 K), what is the value of Kp for this reaction?

7.98 grams of are produced if 10.7 grams of are reacted.

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)  

Putting values in equation 1, we get:

 

The chemical equation for the reaction is

By Stoichiometry of the reaction:

2 moles of produce = 1 mole of

So, 0.100 moles of produce= of  

Mass of =  

Hence 7.98 grams of are produced if 10.7 grams of are reacted.
