AP Chemistry Practice Question 1
2ClF(g) + O2(g) ↔ Cl2O(g) + F2O(g) &DELTA;H = 167 kJ/molrxn
During the reaction above, the product yield can be increased by increasing the temperature of the reaction. Why is this effective?
Correct Answer: A
A The reaction is endothermic, meaning energy is a reactant (appears on the left side of the equation). Adding stress to the left side increases the rate of the forward reaction, creating more products.
