Thermal Heat Engine

A heat engine using a 2.0 mol of a diatomic gas goes through the following "triangular" cycle on the PV diagram.

1---2 Straight line from 400kPa, 0.025m³ to 600kPa, 0.050m³ (I found T= 602K)

2---3 Isochoric decompression at 0.050m³ from 600kPa to 400kPa (I found T = 1807K)

3---1 Isobaric contraction at 400kPa from 0.050m³ to 0.025m³ (I found T = 1205K)

a) Sketch this triangular PV diagram with axes properly labeled.

b) Calculate the three temperatures T1, T2, T3 (not sure if mine are correct)

c) Calculate delta U, Wsys and Q and for each segment of the cycle

d) What is the thermal efficiency of this engine?
