predict the change in entropy of the surrounding for an endothermic reaction {Ans: Because the temperature will go down, the entropy of the surrounding decreases}What is the symbol for the change in enthalpy {Ans: Change in H}Is there a correlation between the change in enthalpy and the change in entropy for a system {Ans: No correlation. Some exothermic reactions have + chance in S. some have - change in S. Some endothermic reactions have + change in S. some have - change in S}What does coupled with mean {Ans: Exergonic processes are often coupled with endergonic.}Would the change in S term in the Gibbs free energy equation (change in G= change in H- T change in S) be positive or negative {Ans: Increase in entropy= positive}Hat is a spontaneous process {Ans: They will occur without any additional work being done on the system.}
