Consider the following equilibria 2CH4(g) C2H6(g) + H2(g) Kc1 = 9.5 × 10-13
CH4(g) + H2O(g) CH3OH(g) + H2(g) Kc2 = 2.8 × 10-21
Choose the best answer to describe how to obtain the following reaction:
2CH3OH(g) + H2(g) C2H6(g) + 2H2O(g) from the following equilibria
First reaction: 2CH4(g)C2H6(g) + H2(g)
Second reaction: CH4(g) + H2O(g)CH3OH(g) + H2(g)
Reverse the second reaction and double it. Next, add the first and second reactions together to obtain the desired reaction.
Add the first and second reactions together to obtain the desired reaction.
Multiple the first and second reactions to obtain the desired reaction.
