Given N2(g)+O2(g)<--> 2NO(g) Keq=8.00 *10-2 at 500 C
In a 2.00L flask, 0.4 mol of N2 and 0.4 mol of oxygen gas, O2, reacted to equilibrium. Establish the equilibrium concentration of all the gases.
(Answer: [N2]=0.175 mol/L; [O2] = 0.175 mol/L; [NO] = 0.0496 mol/L) This one has got a quadratic I can't figure out
My first step: $\frac{\left(2x\right)}{\left(0.2-x\right)^2}=0.08$(2x)(0.2−x)2 =0.08
My second step: $0.08\cdot\left(.2-x\right)\left(.2-x\right)=2x$0.08·(.2−x)(.2−x)=2x
Don't know what's next

Given the reaction PCl5(g)<--> PCl3(g)+Cl2(g)
In a 1.00 L flask, 0.72 mol of PCl5 and 0.18 mol of PCl3 are mixed together. Reaction occurrred to equilibrium and tests showed that 0.60 mol of PCl5 was now present. Calculate the Keq value.
(Answer: 6.0*10-2)although I cannot figure out how to find this without a given value from Cl2.

I've been trying to figure out why $f\ left(x\ right)=\ SQRT{x+2}$ƒ (x)=√x+2 IS a shift left 2. I keep thinking that it IS +2 and that means right 2.
