Two moles of compound P were placed in a sealed container. The container was heated and P was partially decomposed to produce Q and R only. A dynamic equilibrium between P, Q and R was established. At equilibrium x moles of R were present and the total number of moles present was (2+x/2). What is the equation for this reversible reaction?
AP ⇌ 2Q + R
B2P ⇌ 2Q + R
C2P ⇌ Q + R
D2P ⇌ Q + 2R
✓ Correct answer
D: 2P ⇌ Q + 2R
