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:
An object at rest is not moving unless and unbalanced force moves it. ... motion will continue to move at a constant speed in the same direction forever ... But, it will take the harsh unbalanced force of your foot for the rock to move. ... That same amount of small force was NOT big enough for the carriage to pull
Explanation:
Answer:
In writing the electron configuration for nitrogen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for N goes in the 2s orbital. The remaining three electrons will go in the 2p orbital. Therefore the N electron configuration will be 1s22s22p3.
Explanation:
hope you get it right:)
Answer:
the answer is Z b/c wehave to forces and they have different direction. then search the sum of the forces. thus we gain 40 N to right.
The list of options to answer this question is:
A.kinectic energy is transformed into thermal energy.
B.electrical energy is transformed into potential energy.
C.potential energy is transformed into kinectic energy.
D.mechanical energy is transformed into chemical energy.
The answer is the option A. A.kinectic energy is transformed into thermal energy.
As you know energy cannot be lost but transformed.
When friction force acts over the tyres it increases the speed of the particles in the tyres which is thermal energy, this thermal energy increase comes from kinetic energy loss.
