The graph below shows how the temperature and volume of a gas vary when the number of moles and the pressure of the gas are held
DedPeter [7]

Answer:

Option C. By increasing the temperature

Explanation:

From the graphical illustration above, we see clearly that the volume and temperature of the gas are directly proportional. This implies that as the temperature increases, the volume will also increase and as the temperature decreases, the volume will also decrease. This can further be explained by using the ideal gas equation as shown below:

PV = nRT

P is the pressure.

V is the volume.

n is the number of mole.

R is the gas constant.

T is the temperature.

PV = nRT

Divide both side by P

V = nRT/P

Since n and P are constant, the equation above becomes:

V & T

V = KT

K is the constant.

The above equation i.e V = KT implies that:

As T increases, V will also increase and as T decreases, V will also decrease.

Considering the question given above,

The volume of the gas can be increased if the temperature is increased.

A reaction mixture initially contains 0.86 atm NO and 0.86 atm SO3. Determine the equilibrium pressure of NO2 if Kp for the reac
dlinn [17]

Explanation:

Reaction equation for this reaction is as follows.

     NO(g) + SO_{3}(g) \rightarrow NO_{2}(g) + SO_{2}(g)

It is given that K_{p} = 0.0118.

According to the ICE table,

              NO(g) + SO_{3}(g) \rightarrow NO_{2}(g) + SO_{2}(g)

Initial:           0.86      0.86               0            0

Change:          -x          -x                 +x           +x

Equilibrium:  0.86 - x   0.86 - x         x           x

Hence, value of K_{p} will be calculated as follows.

           K_{p} = \frac{P_{NO_{2}} \times P_{SO_{3}}}{P_{NO} \times P_{SO_{3}}}

         0.0118 = \frac{x \times x}{(0.86 - x)^{2}}

             x = 0.084 atm

Thus, we can conclude that P_{NO_{2}} is 0.084 atm.

aleksandrvk [35]
H20, water has hydrogen bonding because of the H-O linkage. NH3 is a polar covalent compound and has also hydrogen bonding because of N-H bonding. CH4, methane is a non-polar covalent compound, hence the forces existing is London dispersion force.

If a reaction produces 1.506 kJ of heat, which is trapped in 30.0 g of water initially at 26.5 C on a clorimetr liake hat in Fig
Dvinal [7]

<u>Answer:</u> The final temperature of water is 38.5°C

<u>Explanation:</u>

To calculate the amount of heat released or absorbed, we use the equation:

q=mc\Delta T

where,

q = heat absorbed = 1.506 kJ = 1506 J   (Conversion factor: 1 kJ = 1000 J)

m = mass of water = 30 g

c = specific heat capacity of water = 4.184 Jl/g.°C

\Delta T = change in temperature = T_2-T_1=T_2-26.5^oC

Putting values in above equation, we get:

1506J=30g\times 4.184J/g.^oC\times (T_2-26.5^oC)\\\\T_2=38.5^oC

Hence, the final temperature of water is 38.5°C
