MATLAB How Can I Code the Rate of Reaction in MATLAB?

AI Thread Summary
The discussion focuses on coding a reaction kinetics model in MATLAB, specifically for a substrate A converting into a product B. The model involves defining initial concentrations for A and B, and calculating the reaction quotient Q to determine the reaction's status. The reaction is active when Q is less than the equilibrium constant k, and stops when Q equals k. The rate of change of A is given by a differential equation, leading to an exponential decay model for A over time. The change in B is directly related to the change in A, with a stoichiometric factor Y. The time variable t is defined with a range from 0.001 to 1 ms. The discussion suggests using the ode45 function in MATLAB, which implements the Runge-Kutta method for solving ordinary differential equations, to simulate the concentrations of A and B over time and plot the results.

Can Anybody help to code this in matlab

A->B --- A is Sbbstrate here and B is Product
Y[/a]=stiochimetric
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 ]

A=Conc_A(t)
B=Conc_B(t)

Plot(t,A,B)

look up RK45
 
I think the Matlab command is ode45 for an RK4-type algorithm.
