Answer:

The concentration of CH₃OH in equilibrium is [CH₃OH] = <em>2,8x10⁻¹ M</em>

Explanation:

For the equilibrium:

CO (g) + 2H₂(g) ⇄ CH₃OH(g) keq= 14,5

Thus:

14,5 = \frac{[CH_{3}OH]}{[CO][H_{2}]^2}

In equilibrium, as [CO] is 0,15M and [H₂] is 0,36M:

14,5 = \frac{[CH_{3}OH]}{[0,15][0,36]^2}

Solving, the concentration of CH₃OH in equilibrium is:

<em>[CH₃OH] = 0,28M ≡ 2,8x10⁻¹ M</em>

I hope it helps!

What is the ph of a solution made by mixing 25.00 ml of 0.100 m hcl with 40.00 ml of 0.100 m koh? assume that the volumes of the
Digiron [165]
<span>Answer: The HCl and KOH will react until one or the other is gone. As you have a larger volume of an equal concentration of HCl, the KOH will go first. moles HCl = 0.04000 L * 0.100 M = 0.00400 moles moles KOH = 0.02500 L * 0.100 M = 0.00250 moles moles HCl left = 0.00400 - 0.00250 = 0.00150 moles Your total volume is now 65.00 mL, so the [HCl] = 0.00150 moles / 0.06500 L = 0.0231 M = [H+] pH = -log [H+] = -log (0.0231) = 1.64</span>
