For the reaction H2(g) + 12 ) At a temperature of 298 K, the equilibrium concentrations are [H2) = 0.45 M; [12] = 0.050 M; and [HI] = 0.13 M, respectively. What is K? A) 23 B) 111 C) 9.0 x 103 D) 0.75 11. A system is at equilibrium when A) K< B) 4Gº=0 C) E°>0 D) All of the above 12. A Brønsted-Lowry base A) is a proton donor B) is a proton acceptor C) is always colored D) is formed by combustion 13. A solution has an [H'] = 0,000132 M. The pH of the solution is A) 3.9 B) 6.3 C) 2.7 D) 10.1
