Answer:
The value of Kc is 9.33 * 10^-17
Explanation:
Step 1: Data given
Temperature = 1000 K
N₂O₄ (g) ⇌ 2 NO₂ (g) Kc = 1.5 * 10^6
N₂ (g) + 2 O₂(g) ⇌ 2 NO₂ (g) Kc = 1.4 * 10^-10
Step 2: Calculate Kc for N₂ (g) + 2 O₂ ⇌ N₂O₄
N₂O₄ (g) ⇌ 2 NO₂ (g) Kc = 1.5 * 10^6
2 NO₂ (g) ⇌ N₂O₄ (g) = 1/Kc = 1 / 1.5 * 10^6 = 6.67 *10^-7
N₂ (g) + 2 O₂(g) ⇌ 2 NO₂ (g) Kc = 1.4 * 10^-10
Kc = Kc1 * Kc2
Kc = (6.67 *10^-7) * (1.4 * 10^-10)
Kc = 9.33 * 10 ^-17
The value of Kc is 9.33 * 10^-17
Carbon and tungsten are the most common heat resistant elements known. Their melting points are approximately 3400 to 3800 degrees Celsius. Ceramic materials as well are known to be heat resistant inorganic solids. Ceramics are made up of metallic and nonmetallic elements.
Answer:
Kp = P(SO2) * P(O2) / P(SO3)
Explanation:
The equation is given as;
SO3(g) --> SO2(g) + O2(g)
In the pressurer equilibrium constant expression, only the gaseous entities are considered.
It is given as;
Kp = P(products) / P(reactants)
Product are SO2(g) and O2(g)
Reactant is SO3(g)
Kp = P(SO2) * P(O2) / P(SO3)
