Solution: Given the chemical reaction: 4 H3PO4 (aq) ⇌ 6 H2 (g) + 8 O2 (g) + P4 (s)              Kc = 1.35 X 10  −12 Which direction will the reaction move if there is initially 0.25 M H 3PO4, 0.0020 M H2, 0.1

Problem

Given the chemical reaction:

4 H3PO4 (aq) ⇌ 6 H2 (g) + 8 O2 (g) + P4 (s)              Kc = 1.35 X 10  −12

Which direction will the reaction move if there is initially 0.25 M H 3PO4, 0.0020 M H2, 0.150 M O2 and 61.94 grams of P4.

a. The reaction will move to the right because Q = 2.1 X 10  -21

b. The reaction will move to the right because Q = 4.2 X 10 −21

c. The reaction will move to the left because Q = 2.1 X 10 −21

d. The reaction will move to the left because Q = 4.2 X 10 −21

e. The reaction will move to the right because Q = 0.0012
