How will the lowering of temperature affect the chemical equilibrium in the system
`2NO+O_(2)hArr2NO_(2), Delta H lt 0`

A

Relative concentration of products and reactants does not change.

B

Relative concentration of products and reactants change.

C

Equilibrium is shift to the left.

D

Equilibrium is shift to the right.

Text Solution

Verified by Experts

The correct Answer is:
B, D
Since `DeltaH lt 0` i.e., `DeltaH lt -ve`
Reaction is exothermic, so lowering of temperature will shift equilibrium towards right. Statement (d) is correct and also the concentration of reactants decreases and products increases. So statement (b) is also correct.

Influence of pressure, temperature, concentration and addition of inert gas on a reversible chemical reaction in equilibrium can be explained by formulating the expression for equilibrium constant K_(c) or K_(p) for the equilibrium. On the other hand Le Chatelier principle can be theoretically used to explain the effect of P , T or concentration on the physical or chemical equilibrium both. For a reversible reaction: 2NO_((g))+O_(2(g))hArr2NO_(2(g)) the rate expression is given as ((dx)/(dt))_("net")=2.6xx10^(3)[NO]^(2)[O_(2)]-4.1[NO_(2)]^(2) . The equilibrium constant of reaction is:
