It is my understanding that Oracle RAC is actually running the database on all nodes concurrently, so if you stop node1, then all transactions and traffic will continue to be processed on node2.
This assumes that the TNS names on all clients are correctly configured so that clients will be aware that RAC is in play and that transfer will take place. You will have tested this when building and deploying your application, I'm sure. If there is an unexpected crash, then I'm assuming that your application will seamlessly continue.
Would you have the confidence to crash your node1 server? If not then that would suggest that this has never been tested.

CRASH(8) BSD System Manager's Manual CRASH(8)
NAME
crash -- examine and debug system images
SYNOPSIS
crash [-M core] [-N kernel]
DESCRIPTION
The crash command is used to examine and debug system images.
If run without any arguments, crash operates on the running system.
The options are as follows:
-M core Operate on the specified crash dump instead of the default /dev/mem. Crash dumps should be from the same version of the system
and same machine architecture as the running version of crash, and must be uncompressed.
-N kernel Extract the name list from the specified kernel instead of the default /dev/ksyms.
The command syntax used by crash is the same as the in-kernel debugger. See the ddb(4) manual page for more information.
Operations and facilities that require a running system, such as breakpoints, are not supported by crash.
crash does not provide pagination. However, by using the pipe symbol, output may be sent to commands available from the shell. For example:
crash> ps | more
crash> ps | grep ioflush
SEE ALSO
ps(1), vmstat(1), ddb(4), pstat(8)
HISTORY
The crash command appeared in NetBSD 6.0.
