The equilibrium constants for the chemical reaction
N₂(g) + O₂(g)

2NO(g) are K_P = 1.1 × 10^–3 and 3.6 × 10^–3 at 2,200 K and 2,500 K, respectively.
Which one of these statements is true?
◦ The reaction is exothermic, ΔHº < 0.
◦ The partial pressure of NO(g) is less at 2,200 K than at 2,500 K.
◦ K_P is less than K_c by a factor of (RT).
◦ The total pressure at 2,200 K is the same as at 2,500 K.
◦ Higher total pressure shifts the equilibrium to the left.
