Question

For the reaction, A(g)⇋2B(g) , Kc=7.0 . A reaction mixture at equilibrium contains [A]=2.3M . What is the concentration of B in the reaction mixture?

Express the molarity to two significant figures and include the appropriate units.

Answer 1

Answer:
`[B]=16 \text{ M}`

Step-by-step explanation:

`K_c=([B])/([A])\\\\7.0=\frac{[B]}{2.3 \text{ M}} \\ \\`

`[B]=16 \text{ M}`
