Answer:
Kp for the reverse reaction is 76.9
Explanation:
Step 1: Kp at 1000 K = 0.013
Step 2: The balanced equation
2NO (g) + Br2 (g) ⇆ 2NOBr (g)
2NOBr (g) ⇆ 2NO (g) + Br2 (g)
Step 3: Calculate Kp
Kp for the reaction 2NO (g) + Br2 (g) ⇆ 2NOBr (g)
Kp = p(NOBr)²/(pBr2)*(pNO)²
Kp = 0.013
Kp for the reverse reaction 2NOBr (g) ⇆ 2NO (g) + Br2 (g)
Kp' = (pBr2)*(pNO)² /p(NOBr)²
Kp' = 1/Kp = 1/0.013 = 76.9
Kp for the reverse reaction is 76.9
Answer: CORRECT answer is A
Cl/S\Cl
Explanation:
A P EX
Answer:
35Cl = 75.9 %
37Cl = 24.1 %
Explanation:
Step 1: Data given
The relative atomic mass of Chlorine = 35.45 amu
Mass of the isotopes:
35Cl = 34.96885269 amu
37Cl = 36.96590258 amu
Step 2: Calculate percentage abundance
35.45 = x*34.96885269 + y*36.96590258
x+y = 1 x = 1-y
35.45 = (1-y)*34.96885269 + y*36.96590258
35.45 = 34.96885269 - 34.96885269y +36.96590258y
0.48114731 = 1,99704989y
y = 0.241 = 24.1 %
35Cl = 34.96885269 amu = 75.9 %
37Cl = 36.96590258 amu = 24.1 %
The correct answer would be C. A blank page <span>is a non-example of volume. Volume is the expression of size for 3D objects. It has the measurement of a distance raised to the power of three.
