Answer 1

Answer #1

a. if ln[A] vs Time , slope is -ve indicates first order reaction

K = - slope

= - (-0.0045)

= 0.0045 s-1

b. rate = K[A]

c. half-life(T1/2) = 0.693/k = 0.693/0.0045 = 154 sec

d. K = (1/t)ln(a0/a0-x)

0.0045 = (1/225)ln(0.25/(a0-x))

a0-x = concentration after 225 sec = 0.091 M
