Extracted text: Which of the following statements about reaction orders in the rate law expression is incorrect? 62. (a) Their values may equal the stoichiometric coefficients in the balanced equation. (b) Their values may or may not equal the stoichiometric coefficients in the balanced equation. (c) Their values must be experimentally determined. (d) Their values get larger as the temperature is increased. (c) An order equal to zero means there is no concentration dependence with rate. 63. The gas phase reaction A + B → C has a reaction rate which is experimentally observed to follow the relationship rate = k[A]°[B]. The overall order of the reaction (a) is first. (b) is second. (c) is third. (d) is zero. (c) is one-half. A hypothetical reaction X+ 2Y → Products is found to be first order in X and second order in Y. What are the units of k, the specific rate constant, if reaction rate is expressed in units of moles per liter per second? 64. (a) M•s- (b) M-²-s-1 (c) M-³•s (d) M²•s-! (e) M-'•s
