Select each process that produces an increase in the entropy of the system: check all that apply. check all that apply. cao(s) +
skelet666 [1.2K]
2SO2(g)+O2(g)→2 SO3(g), here reaction entropy decreases as the number of gas moles decreases from reactions to products.
HCL(g)+NH3(g)→NH4CL(s), entropy decreases as molecules of gas are converted into solid.
CO2(s)→CO2(g), entropy increases as gas is formed from a solid.
Cao(s)+CO2(g)→Caco3(s), entropy increases as gas is converted into a solid.

0.0625 mol of an ideal gas is contained within a 1.0000 Lvolume container. Its pressure is 142,868 Pa and temperature is X K . W
aliya0001 [1]

<u>Answer:</u> The temperature of the ideal gas is 2.75\times 10^2K

<u>Explanation:</u>

To calculate the temperature, we use the equation given by ideal gas equation:

PV=nRT

where,

P = Pressure of the gas = 142,868 Pa = 142.868 kPa    (Conversion factor: 1 kPa = 1000 Pa)  

V = Volume of gas = 1.0000 L

n = number of moles of ideal gas = 0.0625 moles

R = Gas constant = 8.31\text{L kPa }mol^{-1}K^{-1}

T = temperature of the gas = ?

Putting values in above equation, we get:

142.868kPa\times 1.0000=0.0625mol\times 8.31\text{L kPa }mol^{-1}K^{-1}\times T\\\\T=275K=2.75\times 10^2K

Hence, the temperature of the ideal gas is 2.75\times 10^2K
