This is going to take a while..

1. 2AgI + Na2S --> Ag2S + 2NaI

2. Na3PO4 + 3HCl --> 3NaCl + N3PO4

3. Ba3N2 + 6H2O --> 3Ba(OH)2 + 2NH3

4. TiCl4 + 2H2O --> TiO2 + 4HCl

5. 3CaCl2 + 2Na3PO4 --> Ca3(PO4)2 + 6NaCl

6. 2NaBr + Cl2 --> 2NaCl + Br2

7. Mg(OH)2 + 2HCl --> MgCl2 + 2H2O

If the equilibrium constant for the reaction A 2B C 5/2 D has a value of 4.0, what is the value of the equilibrium constant for
nirvana33 [79]

Answer:

K'=\frac{1}{16}

Explanation:

Hello!

In this case, since the given reaction is:

A+ 2B \rightleftharpoons C+ \frac{5}{2} D

Whereas the equilibrium constant is:

K=\frac{[C][D]^{5/2}}{[A][B]^2} =4.0

However, the new target reaction reverses and doubles the initial reaction to obtain:

2C+5D \rightleftharpoons 2A+4B

Whereas the equilibrium constant is:

K'=\frac{[A]^2[B]^4}{[C]^2[D]^5}

Which suggest the following relationship between the equilibrium constants:

K'=\frac{1}{K^2}

So we plug in to obtain:

K'=\frac{1}{4.0^2}\\\\K'=\frac{1}{16}

Best regards!
