Why do some chemical reactions occur? Select all that apply.
A) so the particles can have less volume
B) so the particles can have less energy
C) so the particles can turn into gas
D) so the particles can be more spread out

24. a sports ball is inflated to an internal pressure of 1.85 atm at room temperature (25 °c). if the ball is then played with outside where the temperature is 7.5 °c, what will be the new pressure of the ball? assume the ball does not change in volume nor does any air leak from the ball a) 0.555 atm b) 1.74 atm c) 1.85 atm d) 1.97 atm

Areaction is first order with respect to reactant x and second order with respect to reactant y. which statement describes the rate law for this reaction?

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
