Chemistry Question on Thermochemistry

At constant T and P, which one of the following statements is correct for the reaction.
CO(g)+12O2→CO2(g)?\text{CO}(g) + \frac{1}{2} \text{O}_2 \rightarrow \text{CO}_2(g)?

A

ΔH=ΔE\Delta H = \Delta E

B

ΔH<ΔE\Delta H < \Delta E

C

ΔH>ΔE\Delta H > \Delta E

D

ΔH is independent of the physical state of the reactants\Delta H \text{ is independent of the physical state of the reactants}

Answer

ΔH<ΔE\Delta H < \Delta E

Explanation

Solution

The correct option is (B): ΔH and ΔS are +ve\Delta H \text{ and } \Delta S \text{ are } +\text{ve}
