1. a) A reaction can spontaneously proceed in the forward direction even if the change in the entropy of a system is negative, as long as the change in the entropy of the surroundings is positive and larger (than the negative change in the system). True or False?

b) The entropy of the universe increases during all chemical and physical processes. True or False?

c) For the hypothetical reaction: A (gas)---->B(liquid), the change in enthalpy is +20J. The reaction will be non-spontaneous in the forward direction at any temperature. True or False?

d) If 30 J of heat energy is being given out by the system under constant pressure conditions, the change in enthalpy of the system is -30 J. True or False?
