Final answer:
The constitutionally granted powers to the vice president do not include the ability to create laws or executive orders; these are presidential powers.
Step-by-step explanation:
The power not given to the vice president by the United States Constitution is the ability to unilaterally create laws or executive orders, the latter being a power reserved for the President. The Constitution does grant the vice president the role of presiding over the Senate, where they may cast tie-breaking votes.
Furthermore, under the 25th Amendment, the vice president is the first in line to succeed the presidency in the event of a vacancy or presidential disability. However, the vice president does not have the constitutional power to issue veto decisions, command the armed forces, or grant reprieves and pardons, which are all powers specifically allocated to the President of the United States.
