A researcher is investigating a catalytic reaction where hexane (CH) is converted to benzene (CH) and hydrogen gas (H) under specific conditions. The reaction is carried out in a closed system at a constant temperature. Initially, 1 mol of hexane is introduced into the system. At equilibrium, the researcher finds that 60% of hexane has been converted to benzene. What is the equilibrium constant (Kc) for this reaction at this temperature? A. 1.5 B. 3 C. 0.75 D. 1.0
