I believe the correct response would be A. Energy being absorbed, as temperature increase must for instance occur for the reaction to occur, this increase in temperature for the reacting substances indicates energy being absorbed as the reaction proceeds.

An anode is an electrode, it can be a metal or another conductor. in an electrochemical cell that is polarized if an electric current flows into it. Electric current flows opposite to the direction of movement of electrons. In electrochemical processes, both galvanic cells (batteries) and electrolysis cells, anodes undergo oxidation.
In contrast to an Anode, a Cathode is an electrode pole in an electrochemical cell that is polarized if this pole is positively charged (so that an electric current will flow out of it, or the movement of electrons will enter this pole).
In galvanic cells or power plants (batteries), the anode is the negative pole. The electrode will release electrons towards the circuit and hence an electric current flows into this electrode and makes it an anode and negative.
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
