Question

a. Given these data for the reaction A + B → C, write the rate-law expression. Use k for the rate constant.) b. What is the value, with units, for the specific rate constant? The specific rate constant- Initial Rate of Initial [A] Initial [B] Formation of C Expt. (M) (M.s-1) 0.30 0.30 0.60 0.20 0.40 0.80 4.0 x 10-5 1.6 x 10-4 2.6 x 10-3

Answer 1

when concentration of A doublled rate increased 4 times.

so with respect to A reaction is second order.

when concentration of B doublled rate increased 4 times.

so with respect to B reaction is second order.

rate law as follows

rate = K [A]²[B]²

K = rate / [A]²[B]²

K = 0.0026 / [0.60]²[0.80]²

K = 0.0026 / [0.36][0.64]

K = 0.0026 / 0.2304

K = 0.011 M^-3s^-1
