(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A mixture of NH_{3}and N_{2}H_{4}is placed in a sealed container at 300K. The total pressure is 0.5atm. The container is heated to 1200K, when both substances decompose completely according to the equations,

2NH_{3}--->N_{2}+3H_{2}

N_{2}H_{4}--->N_{2}+2H_{2}

After decomposition is complete, the total pressure at 1200K is found to be 4.5atm. Find the mole percent of N_{2}H_{4}in the original mixture.

2. Relevant equations

3. The attempt at a solution

I am not getting any idea on how to start.

Please give me some ideas on beginning with it.

Thanks! :)
