Some chemical reactions are reversible, and may reverse even as they react. This can create a state of dynamic equilibrium.
Which of the following equations is correct for the reversible reaction between hydrogen gas and iodine gas forming hydrogen iodide gas?
H2(g) + I2(g) ⇌ HI(g)
H(g) + I(g) ⇌ HI(g)
H2(g) + I2(g) ⇌ 2HI(g)
Which of the following statements about dynamic equilibrium is incorrect?
The amounts of the reactants and products are equal.
The rates of the forward and reverse reaction are equal.
The amounts of reactants and products are constant.
If a reversible reaction is exothermic in the forward direction, what will the reverse reaction be?
