R=8.314;
T=298:10:450
Prxn=1:1:5
for j=1:size(Prxn,2)
syms x
Ka=exp(((46.1)./(R.*T)+0.0993./R));
Kaa=(((2.*x).^2.*(4-2.*x).^2)./((1-x).*(3-3.*x).^3.*(Prxn(j)).^2))-Ka==0;
extent=solve(Kaa,x);
plot(T,extent);
hold on;
end

Extent is still a symbolic by the time you try to plot it. You need to convert it to a double. Since you omitted the definition of T we can't test your code.
