Final answer:
True ,The statement is false as it relates to legal principles of contract law. A rejection of an offer is typically effective when received by the offeror, not when dispatched by the offeree, which contrasts with the mailbox rule that applies to acceptance of offers.
Step-by-step explanation:
The statement "A rejection normally is effective at the time it is dispatched by the offeree" refers to a principle in contract law. In many legal systems, this is true.
According to the mailbox rule, an acceptance of an offer is effective once it is sent out (dispatched) by the offeree, not when it is received by the offeror.
However, the claim made in the student's question about rejection contradicts this rule. A rejection is generally effective when it is received by the offeror, not at the time it is dispatched by the offeree.
Therefore, this statement, as it pertains to a normal reaction within physics, it's been confused with a legal term and is misleading. A normal reaction in physics refers to the perpendicular force exerted by a surface against an object in contact .
