a) Provide equation of K of this reaction, use symbol " ^ " for exponents. That means 1000 = 10^3 and 1/100 is 10^(-2). b) How m

stealth61 [152]

Answer and Explanation:

a. The equation of K of this reaction is shown below:-

3 A + 5 B + 4 C↔5 D + 7 E + F

$K = \frac{(D)^5 (E)^7 (F)}{(A)^3 (B)^5 (C)^4}$

b. The moles of compound F is shown below:-

3 A + 5 B + 4 C↔5 D + 7 E + F

2 moles

Now, the mole of produced is

$= \frac{1}{4} \times \ moles\ of\ c$

Now, we will the value of c by using the above equation

$= \frac{1}{4} \times 2$

After solving the above equation we will get

0.5 moles
