Question

A)

In the temperature range between 25°C and 340°C, the reaction in the previous two questions is (SEE THE PICTURE ATTACHED):

Select one:
a. non-spontaneous
b. You can't tell about the range between 25°C and 340°C
c. spontaneous

B)

When you increase the temperature on the reaction in the previous two questions, the amount of work needed to get the reaction to proceed will:

Select one:
a. increase
b. be unchanged
c. decrease
