Me i beg you i really need endothermic and exothermic reactions are terms describing reactions that absorb thermal energy. true false the amount of energy required to raise the temperature of a swimming pool depends on the mass of water present. true false you have been given two different amounts of the same substance. if given double the amount of moles of one, the amount of heat to vaporize the substance will be halved. true false according to the second law of thermodynamics, energy of the universe must always increase. true false when an object releases thermal energy, the average kinetic energy of the object's molecules increases. true false the gibb's free energy equation shows that it is not enough for the change in enthalpy to be negative for a reaction to be spontaneous. true false according to collision theory, the greater number of effective collisions that occur between reactant particles per second, the greater the rate of reaction. true false in an energy diagram for an exothermic chemical reaction, the total energy change is the difference in energy between the energy of the reactants and the energy of the products. true false an increase in temperature for a reaction with a + δh will shift the equilibrium toward the products. true false in calculating the equilibrium constant for a reaction, the coefficients of the chemical equation are used as exponents for the factors in the equilibrium expression. true false
