What does an increase in temperature do to the reaction rate?
Report an error
question 1 of 5
It increases the concentration of the molecules and
slows down the rate of reaction.
It increases the number of effective collisions
between reactants, raising the reaction rate.
It decreases the number of collisions and the
energy of molecules to limit further reaction.
It decreases the energy of the system, limiting how
much further reaction can occur.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
