The Lineweaver–Burk plot, which illustrates the reciprocal of the reaction rate (1/v)(1/v) versus the reciprocal of the substrate concentration (1/[S])(1/[S]) , is a graphical representation of enzyme kinetics. This plot is typically used to determine the maximum rate, VmaxVmax , and the Michaelis constant, KmKm , which can be gleaned from the intercepts and slope. Identify each intercept and the slope in terms of the constants VmaxVmax and KmKm .

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
