Periodic Table Gradebook Question 17 of 28 Incorrect Map General Chemistry 4th Edition niversity Science Books presented by Sapling Learning Consider the reaction described by the following equation The rate law is rate = kc,H.Br2][r] k-4.76 × 10-3 M-1.s-1 where What are the missing entries in the following table? Initial rate of formation ofC2H4 (M-s-1) 0.00112 0.000558 Run [CHaBrlo (M) [0 (M) 0.242 2 0.242 0.242 0.242 Number Number Number z= 112.78 × 10-4 M.s-1 Previous check Answer Next Exit HintExplanation / Answer
Given rate= K[ C2H4Br2] [I-]
Rate= 4.76*10-3 *[C2H4Br2] [I-]
When Rate= 0.00112 M/s
[I-]= 0.242M
[C2H4Br2]= 0.00112/(4.76*10-3*0.242)=0.972
When [C2H4Br2]=0.242, rate =0.000558 M/sec
[I-]= 0.000558/(0.242*4.76*10-3)=0.484M
When [C2H4Br2]=[I-]=0.242
Rate= 4.76*10-3*0.242*0.242 = 0.000279M/s
