The enthalpy of formation for C6 H6 (I) is 49.0 kJ/mol. Consider the following reaction. 6 upper C (s, graphite) plus 3 upper H subscript 2 (g) right arrow upper C subscript 6 upper H subscript g (l). Is the reaction endothermic or exothermic, and what is the enthalpy of reaction? Use Delta H r x n equals the sum of delta H f of all the products minus the sum of delta H f of all the reactants..

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
