Question

I don't understand how to solve.

Answer 1

Answer:

1. b. increase [NH3].

2. d. 0.01.

Explanation:

Hello!

In this case, for these equilibrium problems, we proceed as follows:

1. Here, we consider the Le C hatelier 's principle applied to a gas-phase reaction in which the reactants side have more number of moles; therefore, increasing the pressure will increase the products side as it has the fewest number of moles, so the answer is b. increase [NH3].

2. Here, we know that the equilibrium constant of the reverse reaction equals the inverse of the equilibrium constant of the forward reaction, thus, we obtain:

$K_{rev}=\frac{1}{K_{for}} =\frac{1}{100}=0.01$

Therefore, the answer is d. 0.01.
