Two reactions are given below.

(i) CO(g)+12O2(g)→CO2(g)CO_{(g)} + \frac{1}{2}O_{2(g)} \rightarrow CO_{2(g)}

(ii) Ag2O(s)→2Ag(s)+12O2(g)Ag_{2}O_{(s)} \rightarrow 2Ag_{(s)} + \frac{1}{2}O_{2(g)}

Which of the following statements is true?

A

For (i) ΔH<ΔE\Delta H < \Delta Eand for (ii) ΔH>ΔE\Delta H > \Delta E

B

For (i) ΔH>ΔE\Delta H > \Delta E and for (ii) ΔH<ΔE\Delta H < \Delta E

C

For both (i) and (ii) ΔH>ΔE\Delta H > \Delta E

D

For both (i) and (ii) ΔH<ΔE\Delta H < \Delta E

Answer

For (i) ΔH<ΔE\Delta H < \Delta Eand for (ii) ΔH>ΔE\Delta H > \Delta E

Explanation

Solution

: For (i) Δng=1−32=−12\Delta n_{g} = 1 - \frac{3}{2} = - \frac{1}{2}

For (ii) Δng=12−0=12\Delta n_{g} = \frac{1}{2} - 0 = \frac{1}{2}
