In the reaction A+2 B - products, when the reaction occurs with a very large excess of B, a plot of the concentration of A versus time gives a straight line. What can be said about the rate law for the reaction? The reaction is zero order with respect to A. Overall, the reaction is first order. The reaction is zero order with respect to B. The rate law is rate = k[A].

Please answer both. 

A catalyst is a molecule that decreases the rate of undesired reactions. А са A catalyst helps to direct the course of a reaction but does not increase the rate. QUESTION 15 In the reaction A+ 2 B products, when the reaction occurs with a very large excess of B, a plot of the concentration of A versus time gives a straight line. What can be said about the rate law for the reaction? The reaction is zero order with respect to A. Overall, the reaction is first order. The reaction is zero order with respect to B. The rate law is rate = k[A]. QUESTION 16 For the reaction (CH 3) 2HCBR + CI (CH 3) 2HCCI + Br ", -> you suspect the reaction is first order with respect to (CH 3) 2HCBr. To confirm your theory, you measure the concentration of (CH 3) 2HCBr at various times during a reaction with a large concentration of chloride. What would you plot to get a linear graph in order to confirm your theory? Concentration versus time 1/[(CH3)2HCB1] versus time Ln[(CH3)2HCBr] versus temperature Ln[(CH3)2HCBR] versus time Click Save and Submit to save and submit. Click Save All Answers to save all answers.
