Thank you everyone for the feedback. Although configuring the default
gateway on PC2 with its own IP address allowed me to ping from PC1 to PC2,
it caused some other problems in a part of the network that I omitted, so I
had to re-configure it back without a default gateway. Let me re-draw the
diagram re-sent:

When PC2 attempts to send a response, it checks its routing table first. No
default gateway, no route to host. Done. It won't check the arp table,
because it the process stops at layer 3 (IP) when it can't find a route to
PC1.
Instead of adding a static arp entry, you could add just a static ip r
Unless you're bridging, ARP doesn't function here the way I _think_ you
think it does.
If PC2 receives an incoming ICMP echo request and it wants to generate
a response, it first compares the network portion of the destination
address to its own subnet. If you're not bridging they will be
