Question

For the reaction at 300 k what is the change in energy for combustion of 1.5 mol of benzene at 27 c

Answer 1

Answer:

Answer: 32.44 kJ of energy will evolve when 7.8 g of benzene is burnt in the air.

Explanation:

Moles of benzene =

According reaction, for 1 mole of benzene -324.4 kJ of energy is reevloved

Then for 0.1 mole of benzene will give:

Negative sign means energy is released.

-32.44 kJ of energy will evolve when 7.8 g of benzene is burnt in the air.
