Hi Hassan,
Firstly, as you are defining all the variables inside the function, you do not need to pass them as the function's arguments.
Secondly, you are getting an error as you did not define the variable 'C' in your code. Have a look at the following code.
function dCdt = F_O()
t = 300;
Ce = 100;
C = 1; % Define the variable 'C' by giving it some value. As an example I gave C=1.
kLa = 0.0285;
dCdt = (kLa*Ce-C)/t;
Hope this helps!
