Answer:
a. 
b. K = 192.9
c. Products are favored.
Explanation:
Hello!
a. In this case, according to the unbalanced chemical reaction we need to balance HCl as shown below:

In order to reach 2 hydrogen and chlorine atoms at both sides.
b. Here, given the concentrations at equilibrium and the following equilibrium expression, we have:
![K=\frac{[HCl]^2}{[H_2][Cl_2]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BHCl%5D%5E2%7D%7B%5BH_2%5D%5BCl_2%5D%7D)
Therefore, we plug in the data to obtain:

c. Finally, we infer that since K>>1 the forward reaction towards products is favored.
Best regards!
