Nitrogen dioxide, no2(g) (30hf = 33.84 kj/mol), is decomposed according to the following reaction: what is the enthalpy change when 2.50 mol of nitrogen dioxide decomposes?

The enthalpy change when 2.50 mol of nitrogen dioxide decomposes is 84.6 kJ/mol.

Explanation:

Enthalpy of the formation of

Enthalpy of decomposition when one mol of nitrogen-dioxide decomposes.

When 1 mol of decomposes it gives = -33.84 kJ/mol

When 2.50 mol of nitrogen-dioxide decomposes to give:

The enthalpy change when 2.50 mol of nitrogen dioxide decomposes is 84.6 kJ/mol.
