If the offeror withdraws the offer prior to acceptance, what happens?

If the offeror withdraws the offer prior to acceptance, the offer is revoked and there is no longer a possibility of forming a contract. The withdrawal effectively ends the offer and makes it impossible for the offeree to accept. If the offeree has already communicated their acceptance to the offeror, the withdrawal of the offer will not have any effect, as the acceptance will have already formed a contract.
