Answer:
The Equilibrium will shift towards the left.
Explanation:
The reaction for the formation of nitric oxide is follows,
Expression for reaction quotient is as follows,
![Q=\frac{[NO]^2}{[N_2][O_2]}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BNO%5D%5E2%7D%7B%5BN_2%5D%5BO_2%5D%7D)
Putting the values according to the data given and calculating reaction quotient for the reaction
So, the reaction quotient is 0.16.
and the value of K is 0.01 .
Q>K
Since the value of K is less than Q, therefore the reaction will shift towards left.
Option #2 because gas can take up a lot of space and the particles can spread out more. think of fog its a gas and it can spread out over a big area and its hard for the sun to shine through enough to heat it up and evaporate it.<span />
Answer:
h. 37.5 cm³
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.
</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and P are constant, and have different values of V and T:
<em>(V₁T₂) = (V₂T₁). </em>
V₁ = 50.0 cm³, T₁ = -73°C + 273 = 200 K,
V₂ = ??? cm³, T₂ = -123°C + 273 = 150 K.
∴ V₂ = (V₁T₂)/(T₁) = (50.0 cm³)(150 K)/(200 K) = 37.5 cm³.
- <em>So, the right choice is: </em><em>h. 37.5 cm³.</em>
We need to examine the balancing coefficients of this equation.
<span>4 NH3 + 5 O2 → 4 NO + 6 H2O
From the above equation, it is clear that the formation of 4 moles of NO is accompanied by the formation of 6 moles of H2O.
This means that the ratio between NO:H2O is 2:3
Based on this, if 4.5 moles of H2O are formed then number of NO moles formed (given the symbol n) will be calculated as:
n = 4.5 x (2/3) = 3 moles (cross multiplication)
