Rate of Reaction in matlab

  1. Apr 3, 2013 #1
    Can Anybody help to code this in matlab

    A->B --- A is Sbbstrate here and B is Product
    Initial values are A[0] and B[0]
    Q= reaction quotient

    R=active if Q<k ----- R is reaction
    R=Stops if Q=k
    t=? ------ t is the time

    d[A][/dt]= -kA Conc_A(t,A[0],K) and it return A
    A=A[0] e[-k][t-t[0]]

    And for B
    ΔB = YΔA
    ΔB=B-B[0] = (A[0]-A)Y Conc_B (B[0],Y,A[0],A) gets A and Return B
    B=B[0] + (A[0]-A)Y

    t=[0.001 0.002 0.003...... 1ms ]

    look up RK45

    I think the Matlab command is ode45 for an RK4-type algorithm.
