A reaction A(g)⇌B(g)has an equilibrium constant of 1.0×10−4 For which of the initial reaction mixtures is the small approximation most likely to apply? Explain why.

4. [A] = 0.10M; [B] = 0.00M

Explanation:

Hello,

In this case, the following options are missing:

1. [A] = 0.00M; [B] = 0.10M

2. [A] = 0.0010M; [B] = 0.00010M

3. [A] = 0.10M; [B] = 0.10M

4. [A] = 0.10M; [B] = 0.00M

Therefore, since the equilibrium constant is small, one could make up that at the beginning there is no B since not too much A is consumed during the reaction, consequently, the answer is:

4. [A] = 0.10M; [B] = 0.00M

In fact, in this case would be 0.00001M which is the smallest one from the given options, considering:

Best regards.

alienation, transformation, consumption, and the relativity of truth.

you can choose any one of these, they are all important themes.

these themes reflect the distinct sensibilities of both the modernist and postmodern aesthetic movements. (from google, you should paraphrase)

hope this !
