Answer:
Q>> K
the reaction will proceed to the left
Explanation:
Step 1: Data given
K = 0.154
Number moles CH4 = 6.70 moles
Number of moles C2H2 = 4.05 moles
Number of moles H2 = 10.05 moles
Volume = 5.20 L
Step 2: Calculate concentration of CH4
Concentration = moles / volume
[CH4] = 6.70 mol / 5.20 L = 1.29 M
Step 3: Calculate concentration C2H2
[C2H2] = 4.05 mol / 5.20 L = 0.779 M
Step 3: Calculate concentration H2
[H2] = 10.05 mol / 5.20 L = 1.93 M
Q = [C2H2] [H2]³ / [CH4]²
Q = 0.779 ( 1.93)³ / ( 1.29)² = 3.37 >> K
Q>> K
the reaction will proceed to the left
