The following reaction has Kp = 109 at 25°C. 2 NO(g) + Br2(g) equilibrium reaction arrow 2 NOBr(g) If the equilibrium partial pr
kati45 [8]

<u>Answer:</u> The equilibrium partial pressure of NO is 0.0034 atm

<u>Explanation:</u>

For the given chemical equation:

NO(g)+Br_2(g)\rightleftharpoons 2NOBr(g)

The expression of K_p for above equation follows:

K_p=\frac{(p_{NOBr})^2}{p_{NO}\times p_{Br_2}}

We are given:

Equilibrium partial pressure of Br_2 = 0.0159 atm

Equilibrium partial pressure of NOBr = 0.0768 atm

K_p=109

Putting values in above equation, we get:

109=\frac{(0.0768)^2}{p_{NO}\times 0.0159}\\\\p_{NO}=0.0034atm

Hence, the equilibrium partial pressure of NO is 0.0034 atm

How many moles are there in<br> 15 grams of:<br> CaCO3<br> 204 grams of:<br> Al203
DerKrebs [107]

1) moles = mass/mR

CaCO3 Mr = 40 + 12 + (16×3)

= 52 + 48

= 100

mass = 15

so the moles would be 15 ÷ 100

which is 0.15 moles of CaCO3

2) moles = mass ÷ Mr

Mr of Al2O3 = 27 + (16×3)

= 27 + 48

= 75

mass = 204

so the moles would be 204/75 which is 2.72 moles of Al2O3

What causes a metal spoon in a pot of boiling soup to become hot? And why?
mamaluj [8]
Conduction causes it to become hot, the molecules in the hot soup want to be on the cold spoon so they move to it, making the spoon hot.
