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:
4590 joules
Explanation:
First of all, you need to know the specific heat (C) of the isopropyl alcohol which has the value of 3 kJ /kg°C.
This is an easy calorimetry problem. The formula is Q = m . C . ΔT.
Where m is the mass of compound and ΔT the difference of T°
ΔT = Final T° - Initial T°
Let's replace data, and firstly, we convert the mass of alcohol from g to kg, because the units of the Specific heat
25 g . 1kg /1000g = 0.025kg
Q = 0.025 kg . 3 kJ/kg°C (82.4°C - 21.2°C)
Q = 4.59 kJ
If we want the value in joules, we make the conversion:
4.59 kJ . 1000 J/ kJ = 4590 J
Answer:
The given statement is true.
Explanation:
The given statement is true.
As per an estimate, to convert graphite into diamond nearly 1 billion to 3.3 billion years of time is required.
Graphite converts into diamond when high-pressure is applied deep in the earth core.
