For the reaction

o(g) + o2(g) → o3(g)
δh = −107.2 kj/mol

given that the bond enthalpy in o2(g) is 498.7 kj/mol, calculate the average bond enthalpy in o3.

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
