7) The first order process A?B is followed by the parallel first-order processes
k?
k?
B?C and B?D and the system is modelled by the equations
d(a-x)
--- = -k?(a - x), \frac{dy}{dt} = k?(a - x) - (k? + k?)y, \frac{dz}{dt} = k?y, \frac{dw}{dt} = k?y
dt
where (a-x),y,z,w are the amounts of A,B,C,D respectively at time t. Given the initial
conditions x=y=z=w=0 at t=0 find the amount of C as a function of time.
