Can someone please help me to understand this ( please detailed solution = clear handwriting). (e) 50 mol of gas with specific heat at constant volume of 20.8 J mor K-1 initial pressure Po and initial temperature To - 300 K, undergoes 2 processes in succession, without returning to the initial state in between: (1) isothermal expansion causing pressure to fall to P 2Po/3 (2) isochoric heating causing pressure to increase back to 2 - Po Find the total change...
Can someone help me, I dont know how to approach this question. Thank you so much. In a thermochemistry experiment the reaction of 0.0857 g of an unknown metal and an excess of 4.0 M HCl resulted in a 0.210 mL decrease in the volume of an ice/water mixture in an ice calorimeter. Calculate the enthalpy of this reaction per 1 g of metal reacted. Needed data: density of water at 273 K = 1.00 g/ml density of ice at...
Can someone please help me understand question 2? I understand the first one, but for some reason I keep getting the second one wrong In the class lecture notes, the result of the first-order perturbation calculation for the energy of lithium was given as E" - 2J12+ILL-K2. This energy is added to the EC value obtained by treating each electron as if it were in an independent hydrogen-like orbital in order to estimate the total energy of the lithium atom....

Hi! Can someone help me with this question? Thank you! How will the activation energy and the rate constant change if a catalyst is added at 323 K? (c) How will the activation energy and the rate constant change if a catalyst is added at 323 K?
Can you please help me understand this for my final!! thank you so much 5. (10 pts) Suppose that the dollar-yen spot exchange rate is $0.0090/\ and the 90-day forward exchange rate is $0.0091/¥. The annual interest rate on US bonds is 6%. a. Assuming that covered interest parity holds, calculate the Japanese annual interest rate on bonds of equivalent risk. b. Suppose now that the annual interest rate on US bonds rose to 8%. Assuming that the Japanese interest...
