give handwritten answer-

A+B -> X (k_x)

A+B -> Y (k_y)

A+B -> Z (k_z)

The substances A and B (with the initial concentration C_A⁰
=3 M and CB
^₀
=1 M) react in parallel (competing) reactions. What are the individual rate constants (k_x,k_y,k_z) knowing that at the end of the reaction the proportions of the X,Y,Z are 8%, 91%, 1%, and after the first half hour the concentration of A becomes 2.2 M.

The answer should be:

kx = 1.73 x 10^(-3)   L/mol*s

ky = 1.97 x 10^(-2)   L/mol*s

kz = 2.17 x 10^(-4) L/mol*s
