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

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

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
