What is the difference in entropy between 1 mole of N2 at standard conditions and 1 mole of N2 at 200 °C when the molar volume is 50 liters? Assume that Cp = 5/2 R and that N2 behaves ideally.

The molar heat capacities for carbon dioxide at 298.0 K are shown below. C₁ = 28.95 J K-¹ mol-1 C₂ = 37.27 J K-¹ mol-1 The molar entropy of carbon dioxide gas at 298.0 K and 1.000 atm is 213.64 J K-1 mol-1. (a) Calculate the energy required to change the temperature of 1.000 mole of carbon dioxide gas from 298.0 K to 340.0 K, both at constant volume and at constant pressure. constant volume kJ kJ constant pressure (b) Calculate the molar entropy of CO₂(g) at 340.0 K and 1.000 atm. JK-1 mol-1 (c) Calculate the molar entropy of CO₂(g) at 340.0 K and 1.201 atm. JK-¹ mol-1

Calculate the standard reaction entropy (∆????∅) at 298 K for the reaction of carbon dioxide with calcium oxide which proceeds according to the following:CaO(?) + CO2(?) → ?aCO3(?)

Consider a process in which 100 kJ of energy is transferred reversibly and isothermally as heat to a large block of copper. Calculate the change in entropy of the block if the process takes place at (i) 0 °C, (ii) 50 °C.
