The Figure Shows A $p V$ Diagram For $0.0061$ Mol of Ideal Gas That Undergoes the Process

The figure shows a $p V$ diagram for $0.0061$ mol of ideal gas that undergoes the process $1 \rightarrow 2 \rightarrow 3$ . What is the pressure $p _ { 2 } ? ( R = 8.31 \mathrm {~J} / \mathrm { mol } \cdot \mathrm { K } )$
$p$ (atm)

A) $15 \mathrm {~atm}$
B) $1.5 \times 10 ^ { 6 } \mathrm {~atm}$
C) $4.9 \times 10 ^ { 5 } \mathrm {~atm}$
D) $4.9 \mathrm {~atm}$
