Question

The equation below shows the reaction between nitrogen and oxygen: N2 (g) + 2O2 (g) + 66KJ → 2NO2 (g)
(a) Is this an exothermic or endothermic reaction? Explain your answer.

Answer 1

Answer:

It is an exothermic reaction .

Explanation:

Because it is absorbing heat (I think as the heat '∆' not mentioned) And endothermic releases heat so there is no release of heat or this '∆' sign at the end of reaction followed by '+' symbol.
