For the Reaction: N₂(g)+ 2 O₂(g)⇌ 2 NO₂(g),K_c = 8

For the reaction: N₂(g) + 2 O₂(g) ⇌ 2 NO₂(g) ,K_c = 8.3 × 10^-10 at 25°C.What is the concentration of N₂ gas at equilibrium when the concentration of NO₂ is five times the concentration of O₂ gas?

A) 3) 3 × 10^{- 11} M
B) 1) 7 × 10^-10 M
C) 6) 0 × 10⁹ M
D) 3) 0 × 10¹⁰ M
