An Ideal Gas Undergoes the Process $a \rightarrow b \rightarrow c \rightarrow a$

Multiple Choice

An ideal gas undergoes the process $a \rightarrow b \rightarrow c \rightarrow a$ shown in the $p V$ diagram. In this figure, $P _ { a } = P _ { c } =$ $3.60 \times 10 ^ { 5 } \mathrm {~Pa} , V _ { b } = V _ { c } = 68.00 \mathrm {~L} , V _ { a } = 35 \mathrm {~L}$ , and $P _ { b } = 5.60 \times 10 ^ { 5 } \mathrm {~Pa}$ . How much work is done by the system in this process?

A) $3300 \mathrm {~J}$
B) $2800 \mathrm {~J}$
C) $3000 \mathrm {~J}$
D) $2300 \mathrm {~J}$
E) $3800 \mathrm {~J}$
