I I wrote a command but for some reason it only prints the enthalpy value of water

R = 8.314; % Ideal Gas Constant

T = 300 : 50 : 1000; % Temperature range from 300 K to 1000 K with increments of 50

% Create Temperature Loop

I = 0; % Initialization of loop variable

for T = 300 : 50 : 1000; % Temperature range from 300 K to 1200 K with increments of 50

I = I + 1; % Loop variable

% Hydrogen enthalpy calculations

hf_h = 0; % Hydrogen enthalpy at the standard state

hs_h = R*(((3.057 * T) + ((1/2) * 2.677E-3 * T^2) - ((1/3) * 5.810E-6 * T^3) + ((1/4) * 5.521E-9 * T^4) - ((1/5) * 1.812E-12 * T^5)) - (3.057 * 298 + ((1/2) * 2.677E-3 * 298^2) - ((1/3) * 5.810E-6 * 298^3) + ((1/4) * 5.521E-9 * 298^4) - ((1/5) * 1.812E-12 * 298^5)));

H_hydrogen = (hf_h + hs_h); % Enthalpy of Hydrogen

% Oxygen enthalpy calculations

hf_o = 0; % Oxygen enthalpy at the standard state

hs_o = R * (((3.626 * T) - ((1/2) * 1.878E-3 * T^2) + ((1/3) * 7.055E-6 * T^3) - ((1/4) * 6.764E-9 * T^4) + ((1/5) * 2.156E-12 * T^5)) - (3.626 * 298 - ((1/2) * 1.878E-3 * 298^2) + ((1/3) * 7.055E-6 * 298^3) - ((1/4) * 6.764E-9 * 298^4) + ((1/5) * 2.156E-12 * 298^5)));

H_oxygen = (hf_o + hs_o); % Enthalpy of Oxygen

% Water enthalpy calculations

hf_w = -241820; % Water enthalpy at the standard state

hs_w = R * (((4.070 * T) - ((1/2) * 1.108E-3 * T^2) + ((1/3) * 4.152E-6 * T^3) - ((1/4) * 2.964E-9 * T^4) + ((1/5) * 0.807E-12 * T^5)) - (4.070 * 298) - ((1/2) * 1.108E-3 * 298^2) + ((1/3) * 4.152E-6 * 298^3) - ((1/4) * 2.964E-9 * 298^4) + ((1/5) * 0.807E-12 * 298^5));

H_water = (hf_w + hs_w) % Enthalpy of Water

% Create new variables to save the new calculated values for hydrogen, oxygen, and water enthalpy at each temperature increment

Hydrogen_Enthalpy(I) = H_hydrogen;

Oxygen_Enthalpy(I) = H_oxygen;

Water_Enthalpy(I) = H_water;

Temperature(I) = T;

end % End Loop

Answer 1

[VBBV]

There is a missing semicolon in this line, which makes it to print for each iteration in for loop

H_water = (hf_w + hs_w); % a semicolon is missing in this line in for loop
