A proton is accelerated to 64.2 MeV per particle. What is this energy in kJ/mol?

Given that the equilibrium distance in H2+ is 106 pm and that of H2 is 74.1 pm. Calculate the internuclear repulsion energy in both cases at Re. Using De(H2+)= 2.79 eV and De(H2) = 4.78 eV, calculate Eel and Re

The fraction recrystallized-time data for the recrystallization at 350°C of a previously deformed aluminum are tabulated here. Assuming that the kinetics of this process obey the Avrami relationship, determine the fraction recrystallized after a total time of 116.8 min. Assume y1 = 0.38 and y, = 0.73. Fraction Recrystallized Time (min) 95.2 126.6 i

Short explanations please.

1. An ideal solution containing 0.1x10-3 m3 of methanol and 0.9x10-3 m3 of benzene moves at a molar average velocity of 0.12 m/s. If the molar flux of benzene relative to the mass average velocity is -1.0 kgmol/m2-s, find the total molar flux of methanol, NA, and the mass average velocity. Assume the density of methanol is 792 kg/m3 and the benzene density is 879 kg/m3.

Determine the supersaturation ratio, S, required to permit 0.5-mmdiameter crystals ofsucrose (MW = 342 and ρc = 1,590 kg/m3) to grow if σs,L = 0.01 J/m2. Assume the temperature is 25°C.

Consider an ideal mixture of just 100 molecules, varying in composition from pure A to pure B. Use a computer to calculate the mixing entropy as a function of NA, and plot this function (in units of k). Suppose you start with all A and then convert one molecule to type B; by how much does the entropy increase? By how much does the entropy increase when you convert a second molecule, and then a third, from A to B? Discuss.

Using the T-xy diagram below estimate the bubble-point temperature (in degrees Celsius) and equilibrium vapor composition associated with 0.275 mole fraction ethanol. b. what happen to the bubble point as the mole fraction of ethanol increase? why? c. Describe what happening after about 0.75 mol fraction ethanol.
