Answer:
ΔG = -105.4 kJ/mol
The system is spontaneous as written.
Explanation:
Step 1: Determine Gibbs free energy of reaction (ΔG)
We use the following expression.
ΔG = ΔH - T × ΔS
where,
ΔG = ΔH - T × ΔS
ΔG = 120.5 kJ/mol - 298 K × 0.7582 kJ/mol.K
ΔG = -105.4 kJ/mol
Step 2: Determine the spontaneity of the system.
Since ΔG < 0, the system is spontaneous as written.
Answer:
Charles's law states that V1 / T1 = V2 / T2. However, you must make sure that T is in Kelvin, not C.
1.19E6 / (11 + 273) = V2 / (113 + 273)
V2 = 1.62E6
Explanation:
Gases expand when heated if the container they are in is flexible. When the gas is heated its molecules move faster and faster. The collisions of the gas particles with the flexible container wall expand.
Answer:
the molecules move more quickly and their average kinetic energy decreases :D
Explanation:
This is an example of Charles’ Law problems, the basic equation is: V1/T1 = V2/T2. One vital thing to recall for all gas law problems is that the temperature must be in Kelvin (not Celsius).
So our given is 10.0 C = 283 K. So
V1/T1 = V2/T2
733/283 = 950/T2
T2 = 367 K
Explanation:
A heterogeneous mixture has particles that are not uniformly distributed, but a homogeneous mixture has particles that are uniformly distributed.
