105- The graph below shows the change in molar concentration of the product for the reaction: $\text{AD(g)} \rightleftharpoons \text{A(g)} + \text{D(g)}$, under two different conditions. Which statement is correct? ($P$ is pressure.)
[Figure: Graph of [AD] vs. temperature (°C), showing two curves $P_1$ and $P_2$, where $P_2$ is above $P_1$]
  1. $P_1 < P_2$ and with decreasing temperature, the value of $K$ increases.
  2. $P_2 < P_1$ and with increasing pressure, the equilibrium shifts to the right.
  3. $P_2 < P_1$ and with decreasing temperature, the amounts of A and D change relative to each other.
  4. $P_1 < P_2$ and with increasing volume of the container, the concentration of gas A and the amount of gas AD increase.
