False, the speed it spins on it's axis determinds the length of day.
The speed it rotates the sun determinds the length of it's year.
Jupiter spins counter clockwise. To be exact, it spins counterclockwise when viewed from above the north pole. That's the same direction of spin as most of the planets, including Earth.
How long it spins on it's axis
retrograde motion
retrograde rotation
Venus takes 243 days to spin once on its axis relative to the background stars, although an apparent day is 116.75 days, since it spins (slowly) in the other direction to Earth and most other planets.

A centrifugal spins milk at high speeds to separate the butterfat the rest of milk.
It's Venus, not Mercury. Mercury spins slowly, but not in a retrograde rotation. Venus spins the opposite way from the other planets, except for one of the outer planets (Uranus).

In our solar system, Jupiters spins fastest of all planets - just under 10 hours to complete a revolution (one day).
