Which of the following can be explained by Le Chatelier's principle?

The reaction $2SO_{2(g)} + O_{2(g)} \rightleftharpoons 2SO_{3(g)} + q$ is favored by:

The equation for the reaction in the figure below is: $H_{2(g)} + I_{2(g)} + \text{heat} \rightleftharpoons 2HI_{(g)}$
At the instant $3 \text{ min}$,what change was imposed on the equilibrium?

The chemical equilibrium of a reversible reaction is not influenced by

Le Chatelier's principle is applicable to:

For the isomerization reaction $cis-2-pentene \rightleftharpoons trans-2-pentene$,the standard free energy change at $400 \ K$ is $-3.67 \ kJ/mol$. If more $trans-2-pentene$ is added to the reaction vessel,then ...........
