In combustion studies of the use of H2 as an alternative fuel, HO is sometimes formed in flames by the reaction, H(g) + 1/2 O2(g) <=> HO(g) Use the data below to calculate the value of Kc H2(g) <=> 2 H(g) Kc = 0.00473 1/2 H2(g) + 1/2 O2(g) <=> OH Kc = 0.643 Give your answer to 3 significant figures
