Dead from direct exposure, dead from exposure related inability to control 
the parachute, or at best incapacitated from exposure and rough landing 
injuries.

To survive you will need an insulated jump suit and an oxygen system.  Still 
going to be cold and uncomfortable when you hit the ground, and your business 
clothes will be a little wrinkled, but you will be alive and able to continue 
the mission.

For HALO jumps you cn get away with an insulating under layer and smaller air 
supply.

>And how big such a chute is.

US Forces use the standard MC-5 Static Line/Free-Fall Ram Air Parachute 
System for all freefall jumps from 3000ft AG to 30,000ft MSL.  This is a 
standard 7-cell 370sq ft parachute like most civilian rigs.  Rate of descent 
is 8-18 ft/second.
