The MKS system uses the same fundamental units as the SI system. It uses meter for distance, kilogram for mass, and second for time. These are all present as fundamental units in the SI system.

Fahrenheit is the unit for temperature. Other units include Celsius and Kelvin.

We know that ΔG₀ = – RT lnK_c, where ΔG₀ is the standard Gibbs free energy, R is universal gas constant, T is the temperature and K_C is equilibrium constant; substituting ΔG₀ as -831.4 J/mol, we get lnk = -831.4J/mol divided by -8.314J mol^–1K^–1 × 100K = 1; lnk = 1; K = e¹ = 2.7

We know that ΔG₀ = – RT lnK_c, where ΔG₀ is the standard Gibbs free energy, R is universal gas constant, T is the temperature and K_C is equilibrium constant; substituting ΔG₀ as -2502 J/mol, we get -2502 J/mol = -8.314J mol^–1K^–1 × T ln2 = 2502 J/mol = T = 2502/2.502 = 100 k.

In the equation ΔG = ΔG₀ + RT lnQ, ΔG is the Gibbs free energy, R is the universal gas constant, T is the temperature and Q is the reaction quotient. When Gibbs free energy is zero, the reaction quotient becomes equilibrium constant.

Blood is specialized fluid connective tissue. It consists of plasma, a fluid matrix and the formed elements, which are the erythrocytes or red blood cells, leukocytes or white blood cells and thrombocytes or platelets.

Plasma, which is an element of blood, constitutes 55% of it. The rest 45% consists of the formed elements-the RBCs, the WBCs and the blood platelets. Plasma is straw colored and a viscous fluid.

45% of blood contains the formed elements while 55% of the blood is plasma. The formed elements are the erythrocytes or red blood cells, leukocytes or white blood cells and thrombocytes or platelets.

Hemoglobin is a complex iron containing protein present in erythrocytes or red blood cells. It is red in color and hence, gives erythrocytes its red color. 12-16g of hemoglobin is present in 100ml of blood.

Eosinophils are associated with allergic reactions. They constitute 2-3% of the total number of white blood cells. They resist infections. They also have anti-parasitic and bactericidal activity.
