^{-2}kg of nitrogen is expanded isothermally and reversibly at 300 K from 15.15 *10^{5}Nm^{-2}when the work done is found to be - 17.33 kJ. find the final pressure.pls show log calculations

(molar mass = 30) at 300 K is

a. -187 kJ

b. 18.7 kJ

c. 6.234 kJ

d. -6.234 kJ

for a particular reaction, the system absorbs 6kJ of heat and does 1.5 kJ of work on its surroundings. Calculate change in internal energy and enthalpy of system.
