Question 17 hydrogen is manufactured on an industrial scale by this sequence of reactions: +ch4gh2og ⇌ +cog3h2g k1 +cogh2og ⇌ +co2gh2g k2 the net reaction is: +ch4g2h2og ⇌ +co2g4h2g k write an equation that gives the overall equilibrium constant k in terms of the equilibrium constants k1 and k2. if you need to include any physical constants, be sure you use their standard symbols, which you'll find in the aleks calculator.
