Question

Please help!! I'll give 50 points

The reaction between methane gas and ammonia gas to form hydrogen cyanide has reached equilibrium. What is the effect of adding more ammonia (NH3) gas to the reaction chamber? Here is the equation: CH4 + NH3 + 1.5O2 ⇄ HCN + 3H2O.

It says the answer is that equilibrium will shift to the right. Why is that the answer? Can someone explain it to me?

Answer 1

The equilibrium will shift to the right.

Step-by-step explanation:

• Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.

For the reaction: CH₄ + NH₃ + 1.5O₂ ⇄ HCN + 3H₂O.

Adding NH₃ to the reaction:

• Adding NH₃ will increase the concentration of the reactants side, so the reaction will be shifted to the right (products) side to suppress the increase in the concentration of NH₃.
