For the reaction A (g) → 2 B (g), K = 14.7 at 298 K. What is the value of Q for this reaction at 298 K when ∆G = -20.5 kJ/mol?
harina [27]

Answer:

Q= 245 =2.5 * 10^2

Explanation:

ΔG = ΔGº + RTLnQ, so also ΔGº= - RTLnK

R= 8,314 J/molK, T=298K

ΔGº= - RTLnK = - 6659.3 J/mol = - 6.7 KJ/mol

ΔG = ΔGº + RTLnQ → -20.5KJ/mol = - 6.7 KJ/mol + 2.5KJ/mol* LnQ

→ 5.5 = LnQ → Q= 245 =2.5 * 10^2

3. When two atoms of 2H (deuterium) are fused to form one atom of 4He (helium), the total energy evolved is 3.83 × 10-12 joules.
balandron [24]
3.
∆E = ∆m x c ² ∆m = E / c ² ∆m = 3,83•10^-12 / 3•10^8 ² ∆m = 4,256•10^-29 kg

PLS HELP ME LIKE ASAP<br> In carbonization, why is the fossilized material called a carbon film?
inysia [295]

Answer:

When an organism dies or a leaf falls, it sinks into the earth's layers and decomposes. A carbon film is made when the oxygen, hydrogen and nitrogen of the organism disappear, leaving a thin layer of carbon. This process is known as distillation or carbonization.

Hope it helps!
