Calculate Ke for the following(equilibrium concentrations given below substances)
NH4SH(g) yields NH3(g) + H2S(g) + heat
[.027] [.0234] [.209]
Thank you!
The concentrations didn't line up correctly...they should be:
NH4SH= [.027]
NH3=[.0234]
H2S= [.209]
Thank you!
The boards don't recognize spacing more than one space.
What is it you don't understand? Just write the Ke expression, then substitute the equilibrium concentrations and calculate Ke.
To calculate the equilibrium constant (Ke), you need to use the given equilibrium concentrations of the substances involved in the reaction.
In the given reaction, NH4SH(g) dissociates into NH3(g), H2S(g), and heat. The equilibrium concentrations of the substances are as follows:
[NH4SH(g)] = 0.027 M
[NH3(g)] = 0.0234 M
[H2S(g)] = 0.209 M
The equilibrium constant expression for this reaction can be written as:
Ke = [NH3(g)] * [H2S(g)] / [NH4SH(g)]
Now, you can substitute the given equilibrium concentrations into the expression to calculate the value of Ke.
Ke = (0.0234 M) * (0.209 M) / (0.027 M)
Ke = 0.0234 * 0.209 / 0.027
Ke = 0.191586...
Therefore, the equilibrium constant (Ke) for the given reaction is approximately 0.1916.
Note: Make sure to round your final answer to an appropriate number of significant figures based on the significant figures in the given data.
