Increasing the temperature increases reaction rates because of the disproportionately increase in the number of high energy collisions.
It's only these collisions (possessing at least the activation energy for the reaction)
which results in a reaction!
1) 211m/s
2)240<span>°
3)759,600m or 759.6 km</span>
The answer is 8 because multiplying 7 and 8 is 56
