Thanks for all your help so far!

There's always one problem that gets me on my homework.. could y'all take a look at this one and give me a good way to go about this problem below? Thanks!

from the 1^st reaction:
 p_NOBr / p_Br2^0.5 * p_NO = 5.3

from the 2^nd reaction:
 p_N2 * p_O2 / p_NO² = 2.1 * 10³⁰

asked: p_NOBr² / p_N2 *p_O2 * p_Br2 = ...

Just substitute the 2^nd reaction's K_p equation into the first.

Hint: start by squaring the first reaction's equation.
