PLUS Melone est1 B) This is not the cort ansn is o derod daa corecty and set up the comet relative rate and ? It were performed. The following data were obtained Initial Concentration of NH4CNO Initial Rate of Formation of Urca (mol L1)(mol) 2.4 x 10 5.4 X 104 9.6 x 104 The rate law and rate constant for this reaction are: 0.20 0.30 0.40 O Rate-k [NH4CNO]2 and k = 1.2 x 10-2 L mori S-1 O Rate-k(NH4CN0] and k = 1.2 x 10-2 s-1 O Rate k (NHACNO]2 and k 6.0x103 L mor1 Rate . k [(NH2)2CO]2 and k . 6.0 x 10,3 L mor's Question Attempts: 1 of 3 used LAVE rOR LANTER SUDNIT ANSWER

Explanation / Answer

see the 1st row and 2nd row of table

Rate becomes (9.6*10^-4) / (2.4*10^-4) = 4

concentration becomes 0.40/0.20 = 2

So,

order of NH4CNO is 2

rate law is :

rate = k [NH4CNO]^2

put value from row 1:

rate = k [NH4CNO]^2

2.4*10^-4 mol/L/s = k (0.20 mol/L)^2

k = 6.0*10^-3 L.mol-1.s-1

Answer: option 3
