What type of reaction is 2HI H2 I2?

What type of reaction is 2HI H2 I2?

second order reaction

Is H2 I2 2HI exothermic or endothermic?

H_2(g) + I_2(g) <—> 2HI(g) The forward reaction above is exothermic.

What will be the direction of reaction if concentration of H2 I2 and hi?

If we start with equal initial concentration of H2 and I2, the reaction proceeds in the forward direction and the concentration of H2 and I2 decreases while that of HI increases, until all of these become constant at equilibrium (Fig. 7.5).

What is the equilibrium constant for the reaction H2 g )+ I2 G ⇌ 2HI G at 700 K?

At 700K equilibrium constant for the reaction, H2(g)+I2(g)⇔2HI(g) is 54.8.

What will be the equilibrium constant at 717 K for the reaction?

if K forH2(g)+I2(g)⇔2HI at 717 K is 50.

What is the equilibrium constant for the reaction H2 g )+ I2 G ⇌ 2HI G?

The value of the equilibrium constant, Kc, for the reaction H2(g) + I2(g) ⇔ 2HI (g) at 448°C is 50.5.

What is wrong about equilibrium state?

Catalyst has no effect on equilibrium state.

For which reaction KP is not equal to KC?

Solution : Key idea The reaction for which the number of moles of gasesous products (np) is not equal to the number of moles of gaseous reactants (nR) has different value of Kc and Kp.

What is the equilibrium constant dependent on?

The value of the equilibrium constant for any reaction is only determined by experiment. It does, however, depend on the temperature of the reaction. This is because equilibrium is defined as a condition resulting from the rates of forward and reverse reactions being equal.

Is equilibrium constant dependent on temperature?

Increasing the temperature decreases the value of the equilibrium constant. Where the forward reaction is endothermic, increasing the temperature increases the value of the equilibrium constant. The position of equilibrium also changes if you change the temperature.

Can an equilibrium constant be negative?

When Kc is less than 1, reactants exceed products. When much less than 1 (Kc can never be negative…so when it is close to zero) the reaction hardly occurs at all. 8.2. 3 : The only thing which can change the value of Kc for a given reaction is a change in temperature.

Why is KC not affected by concentration?

The balance of incoming/outcoming energy change the concentration of reactants andproducts but not affect the equilibrium constant: the ratio of the concentrations in the given formula (that changes from reaction to reaction) remains constant, even the reactants and products concentration varies.

Can the equilibrium constant ever be zero?

The equilibrium constant cannot be 0. This is because this implies that the concentration of products is equal to 0 at equilibrium.

What does it mean when Delta G is negative?

A negative ∆G means that the reactants, or initial state, have more free energy than the products, or final state. Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy.

What is S in Chem?

In chemistry, the standard molar entropy is the entropy content of one mole of pure substance under a standard state (not standard temperature and pressure). The standard molar entropy is usually given the symbol S°, and has units of joules per mole kelvin (J⋅mol−1⋅K−1).
