Emma · Answer 1

K, the rate constant = 9.73 * 10^ (-1) / s

Explanation:

r = K * [A]^x * [B]^y

r = Rate = 1.07 * 10^ (-1) / s

K = Rate constant

A and B = Concentration in mol/dm^-3

A = 0.44M

B = 0.11M

x = Order of reaction with respect to A = 0

y = Order of reaction with respect to B = 1

Solving, we get

r / ([A]^x * [B]^y) = K

K = 1.07 * 10^ (-1) / s / (0.44^0 * 0.11^1) = 0.9727

K = 0.9727
