E If a reaction is thermodynamically spontaneous it must have a low activation energy.
D If a reaction is thermodynamically nonspontaneous it will not occur spontaneously. The 2-kg car car will have greater speed and the 1-kg car will have greater kinetic energy. Simultaneously as it nears the ground it loses potential energy.
Gravitational potential energy work done kinetic energy gravitational potential energy and conservation energy of an object such as a ball being lifted above the ground it has gravitational potential energy which is defined as the energy held by an object. If its pegd is doubled then its new kinetic energy will be a. Potential energy also includes other forms.
Potential Energy is defined as the energy stored by a body by virtue of its position relative to others stresses within itself electric charge and other factors. C Activation energy is a kinetic quantity rather than a thermodynamic quantity. A Kinetic energy can be measured in watts.
