7. An increase in the temperature of the reactants causes an increase in the rate of reaction. The best explanation for this behavior is that as the temperature increases, a. the fraction of collisions with total kinetic energy greater than Ea increases. b. the concentration of reactants increases. c. the activation energy remains the same. d. the collision frequency decrease

The kinetic molecular theory of gases predicts pressure to increase as the temperature of a gas increases because: I. the average kinetic energy of the gas molecules increases. II. gas molecules collide more frequently with the container walls. III. there are more molecules per unit volume after raising the temperature. IV. the elasticity of the molecules increases. V. there are less molecules per unit volume after raising the temperature. a. I and II b. I and III c. II and...

from gay-lussac's law, If you increase the temperature of a gas (with constant moles and volume) what do you expect will happen to the pressure? Look up Boyle's Law. For an ideal gas at constant temperature and moles, if you increase the volume of the gas what do you expect will happen to the pressure of the gas? How else is the pressure-volume relationship typically plotted?
