Final answer:
The statement is false. Offers without a specific time for acceptance are not automatically invalid but instead are given a reasonable timeframe based on the situation. Indefiniteness in other terms might impact validity, not just the acceptance period.
Step-by-step explanation:
The statement T/F. Offers that fail to provide a specific time for acceptance are invalid because they are deemed to be indefinite is generally considered false. In the context of contract law, while offers should contain definite terms, the lack of a specific time for acceptance does not automatically render an offer invalid. Instead, if a specific time for acceptance is not provided, a reasonable time for acceptance is implied based on the circumstances surrounding the offer. If the offer is left open for too long, it could be deemed to lapse due to the passage of time or upon the occurrence of certain events which make performance impossible.
An offer that is too indefinite in its terms may be invalid because it lacks the clarity required to form the basis of a contract. However, this does not solely depend on the time for acceptance but also on other factors such as the definiteness of the offer's terms and the intentions of the parties involved. The law aims to enforce and uphold agreements where there is a clear meeting of the minds, and a reasonable interpretation of the offer's terms can often be deduced even without a specific time frame for acceptance.
