The first two steps in the industrial synthesis of nitric acid produce nitrogen dioxide from ammonia: 4 NH3(g) +502(g) = 4 NO(g) +6 H20 (g) 2 NO(g) + O2(g) = 2 NO2 () The net reaction is: 4NH3(g) +702(g) = 4NO2 (g) + 6H2O(g) Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K, and K2. If you need to include any physical constants, be sure you use their standard symbols, which you'll find in the ALEKS Calculator.

Answer from: ciarra31

The equilibrium constant for the overall reaction is $K_1\times (K_2)^2$

Explanation:

The given chemical equations follows:

Equation 1: $4NH_3(g)+5O_2(g)\xrightarrow[]{K_1} 4NO(g)+6H_2O(g)$

Equation 2: $2NO(g)+O_2(g)\xrightarrow[]{K_2} 2NO_2(g)$ ( × 2)

The net equation follows:

$4NH_3(g)+7O_2(g)\xrightarrow[]{K} 4NO_2(g)+6H_2O(g)$

The equilibrium constant for the net reaction will be the multiplication of two above equations.

If the equation is multiplied by a factor of '2', the equilibrium constant of the net reaction will be the square of the equilibrium constant of respective reaction.

The value of equilibrium constant for net reaction is:

$K=K_1\times (K_2)^2$

Hence, the equilibrium constant for the overall reaction is $K_1\times (K_2)^2$

Answer from: Quest

1.consider the following balanced equation and answer parts a through. show calculations for each part.

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
