Answer 1

The reaction quotient Q for the reaction C(s) + H2O(g) ⇌ CO(g) + H2(g) at 1100 K with partial pressures of H2O at 0.250 bar, CO at 0.350 bar, and H2 at 0.500 bar is 0.70.

Step-by-step explanation:

To calculate the reaction quotient Q for the reaction C(s) + H₂O(g) ⇌ CO(g) + H₂(g), we use the partial pressures of the gaseous components. The formula for Q is Q = (PCO * PH2) / PH2O, where P denotes the partial pressure of each gas.

Given the partial pressures are:

• H2O: 0.250 bar
• CO: 0.350 bar
• H2: 0.500 bar

Plugging these values into the formula, we get:

Q = (0.350 bar * 0.500 bar) / 0.250 bar

Q = (0.175 bar²) / 0.250 bar

Q = 0.70

Therefore, the reaction quotient Q for this reaction at 1100 K with the given partial pressures is 0.70.
