Be sure to answer all parts Initial Rate of X M Disappeara

Be sure to answer all parts. Initial Rate of | [X] (M) | Disappearance of Consider the reaction X + Y Z (M) From the data in the table, obtained at 360 K, (M/s) (a) determine the overall order of the reaction-m- 0.053 0.127 1.02 0.254 0.509 0.100.50 0.20 0.30 0.60 tu 0.40 0.20 0.60 0.40 0.30 (b) determine the initial rate of disappearance of X when the concentration of X is 0.20 M and that of Y is 0.50 M Mis Type here to search

Solution

a) when concentration of X alone doublled rate increased by 4 times so with respect to X order = 2

when concentration of Y alone doublled rate also doublled do with respect to Y order = 1

overall order = 2 + 1 = 3

b) first calculate the K from given data

rate law as follows

rate = K [X]² [Y]

K = rate / [X]²[Y]

K = 0.053 / [0.1]² [0.50]

K = 0.053 / 0.005

K = 10.6 M^-2 s^-1

now [X] = 0.20 M

[Y] = 0.50 M

rate = K [X]²[Y ]

rate = 10.6 [0.20]²[0.50]

rate = 0.212 M/s
