Explanation / Answer

For an endothermic reaction: Energy is absorbed

For an exothermic reaction: Energy is liberated

As per the statement, 66.4 kJ of energy is absorbed. Therefore, the given reaction is an endothermic reaction.

The energy absorbed for the mole of reaction is 66.4 kJ.

As per the balanced reaction formation of product is 2 moles.

Calculate the value of q as follows:

66.4 kJ/mol*2 mol = 132.8 kJ

Therefore, the value of q is 133 kJ.
