For the acids, use the formula ph = -log[hbecause hcl has 1 htion per formula unit, h'lequals the
molanty) for water, use what you know about the ph of neutral solutions. for the bases, examine and

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
