In the reaction sequence below, the enzymatic reaction is carried out through the formation of two intermediate complexes. If the speed limiting step v = k5 (ES) 2 in the product formation, separately derive the speed equation of this reaction according to the fast balance and steady-state approach.

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
