Part A; The answer is negative, which is consistent with a (n) decrease in the number of moles of gases.
Part B: The answer is positive, which is consistent with a (n) increase in the number of moles of gases.
Part C: The change is small because the number of moles of gas is constant.
Part D: The answer is negative ,which is consistent with a (n) decrease in the number of moles of gases.
