I believe the correct answer would be reactants. When heat is added to the reaction mixture, the formation of reactants would be favored since the reaction is an exothermic reaction. Hope this answers the question. Have a nice day.

Last friday the atmospheric pressure in our 2nd year lab was measured as 731 mmhg. Calculate the temperature at which water woul

faust18 [17]

Answer:

p1/T1=p2/T2

760mmHg/212°F=731mmHg/T2

T2= 203.91°F

760mmHg/100°C=731mmHg/T2

T2= 96.18°C

Explanation:

You'd have to choose in which units you want to express the temperature.

What is the equilibrium constant expression for the given system?

artcher [175]

<h3>Answer:</h3>

$\displaystyle K_{eq} = \frac{[H_2]^2[O_2]}{[H_2O]^2}$

<h3>General Formulas and Concepts:</h3>

<u>Chemistry</u>

<u>Aqueous Solutions</u>

States of matter

<u>Kinetics</u>

Rate Laws

<u>Equilibrium</u>

Equilibrium Reactions RxN ⇄
Equilibrium Constants
Equilibrium Expression: $\displaystyle K = \frac{[Producst]^{coefficients}}{[Reactants]^{coefficients}}$

<h3>Explanation:</h3>

*Note: Only gases and liquids affect equilibrium

<u>Step 1: Define</u>

[RxN - Balanced] 2H₂O (g) ⇄ 2H₂ (g) + O₂ (g)

<u>Step 2: Identify</u>

[Reactant] H₂O

Coefficient of 2

[Product] H₂

Coefficient of 2

[Product] O₂

Coefficient of 1

<u>Step 3: Write K Expression</u>

Substitute: $\displaystyle K_{eq} = \frac{[H_2]^2[O_2]}{[H_2O]^2}$
