A reaction has an equilibrium constant of 7. 9×103 at 298 k. At 713 k , the equilibrium constant is 0. 77. Do you predict that the enthalpy of the reaction is positive or negative? why?.

not moving. pos accel,

it doesn't. it was imagined up in the middle ages.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
