- What is the change in entropy when 150 mL of cold (278 K) water is added to 150 mL of near-boiling (368 K) water? Ignore any potential heat loss to the surroundings; only consider the water. For water, Cp = 75.3 J K-1 mol-1.arrow_forwardCalculate ΔG° (answer in kJ/mol) for each of the following reactions from the equilibrium constant at the temperature given. (d)CoO(s)+CO(g)⇌Co(s)+CO2(g) T=550°C Kp=4.90×102 (e)CH3NH2(aq)+H2O(l)⟶CH3NH3+(aq)+OH−(aq) T=25°C Kp=4.4×10−4 (f)PbI2(s)⟶Pb2+(aq)+2I−(aq) T=25°C Kp=8.7×10arrow_forwardIn Gibbs free energy, what does the delta G signify?arrow_forward
- For the following reaction 3 experiments have been run and the data collected is in the following table @ 35 degrees Celsius 2 NO2F(g) ---> 2 NO2(g) + F2(g) Experiment [NO2F], M Rates, M/s 1 0.263 0.168 2 0.349 0.223 3 0.421 0.269 a) How long will it take for a 65% NO2F solution to become a 31% NO2F solution @35 degrees Celsius?(Hint: Use mass ratios and assume ~1g/ml for density of solutions to get you started) b) It has been determined that at 75 degrees Celsius the rate constant is 1.046 s-1. Calculate the activation energy for the decomposition of NO2F. [Hint: ]ln?1?2=?a?(1?2―1?1) c) What is the half-life of a 35% solution of NO2F @ 35 degrees Celsius?arrow_forwardWhich of the following correctly explains why the vapor pressure of water has to be included in the calculations? Some of the liquid water evaporates into the gas, and increases the total pressure generated by the trapped gas. As the H2(g) is bubbled up the reaction solution, some of the H2(g) molecules are solubilized by water in the aqueous solution, effectively decreasing the measured pressure above. The pressure contributed by the H2(g) is greater than the measured total pressure because of the contribution of partial pressure of water vapor. The pressure exerted by the evolved H2(g) is reduced because of the co-presence of water vapor, thus Pwater vapor has to be added to Pdry gas.

- Answer the following questions yes or no (Y/N): Is the michaelis-menten equation valid under experimental conditions? Is the michaelis-menten equation only valid for reactions that are at equilibrium? Is extrapolation to Vm inaccurate, but Km is accurately determined in the michaelis-menten equation? Is the michaelis-menten equation nonlinear? Is extrapolation to Vm inaccurate, and therefore Km cannot be accurately determined in the michaelis-menten equation?arrow_forwardFigure 6.8 Look at each of the processes shown, and decide if it is endergonic or exergonic. In each case, does enthalpy increase or decrease, and does entropy increase or decrease?arrow_forwardA reaction at 23°C has ∆G = 1 kJ mol–¹.
