The diagram below shows the different phase transitions that occur in matter. Three bars are shown labeled Solid, Liquid, and Ga

s. They are connected by arrows labeled 1 to 6. Arrow 1 points from liquid to gas; arrow 2 from solid to liquid, arrow 3 from solid to gas, arrow 4 from gas to liquid, arrow 5 from liquid to solid, and arrow 6 from gas to solid. Which arrow would most likely represent the phase change that involves the same amount of energy as arrow 1? 2 3 4 5

H2(g) + CO2(g) + 10 kcal H2O(g) + CO(g)
EleoNora [17]

<u>Answer:</u> The equilibrium constant for the given reaction is 0.8

<u>Explanation:</u>

Equilibrium constant is defined as the ratio of concentration of the products raised to the power its stoichiometric coefficients to the concentration of reactants raised to power its stoichiometric coefficient. It is represented as K_c

For the general equation:

aA+bB\rightleftharpoons cC+dD

The equilibrium constant is represented as:

K_c=\frac{[C]^c[D]^d}{[A]^a[B]^b}

For the given chemical equation:

H_2(g)+CO_2(g)+10 kcal\rightleftharpoons H_2O(g)+CO(g)

K_c for this equation is given by:

K_c=\frac{[H_2O][CO]}{[H_2][CO_2]}

Concentration at equilibrium of

H_2=2mol/L\\H_2O=4mol/L\\CO_2=5mol/L\\CO=4mol/L

Putting values in above equation, we get:

K_c=\frac{4\times 4}{2\times 5}\\K_c=0.8

Hence, the equilibrium constant for the given chemical reaction is 0.8

Acrylonitrile () is the starting material for many synthetic carpets and fabrics. It is produced by the following reaction. If 1
pychu [463]

2C3H6 (g) + 2NH3 (g) + 3O2 (G) -> 2C3H3N (g) + 6H2O (g)

First off.. not a chem board.. but n e way.

This is a limiting reagent problem.

set it up as a DA problem.(Dimension Analysis)

Start with what you want.

you want Grams of acrylonitrile (C3H3N)

so start with that (Using ACL in place of Acrylonitrile.. just for ease of typing)

(g) = (53 g of ACL/1mol ACL) (2 mols ACL/2 mol C3H6)/ (1mol C3H6/42 grams) (15.0 grams)

solve that you wiill get grams of Acrylonitrile created by 15 grams oc C3H6 = 18.9g

Same setup for the two other reactants.

so i did it and for

oxygen I got 11.04 grams

and for Ammonia i got 15.29 grams

So the most you can make is 11.04 grams because if you have ot make any more .. you will have to get more O2 .. but since you have only 10 grams of it .. that is the most u can make in this reaction.

Both the other reactants are in excess.
