The rate of a metal-catalyzed carbonylation reaction, rx + co + oh-→ rcooh + xt, is directly proportional to the concentration of chemisorbed carbon monoxide on the metal catalyst. when the carbon monoxide pressure pco is increased from 100 to 200 mm hg while other reaction conditions are held constant, the rate changes by a factor of 1.5. (a) what will be the expected rate change if pco is increased from 100 to 400 mm hg? support your answer with calculation. (b) if the study is repeated at a higher reaction temperature, will the rate increase corresponding to an increase of pco from 100 to 200 mm hg be greater than, less than, or equal to 1.5?
