Answer:

P represents electrical energy, Q represents thermal energy

Explanation:

I am sorry if I get this wrong, but when I put it in the sentence - A toaster transforms electrical energy into thermal energy - it made sense to me, so I think that is the answer. I am sorry if this does not help.

For the reaction co(g)+2h2(g)<->ch3oh(g) at 700. k, equilibrium concentrations are [h2] = 0.072 m, [co] = 0.020 m, and [ch

SVETLANKA909090 [29]

The balanced equation for the reaction is
CO(g) + 2H₂(g) ⇄ CH₃OH(g)

Since given concentrations are at equilibrium state, the expression for the equilibrium constant, k can be written as
k = [CH₃OH(g)] / [CO(g)] [H₂(g) ]²

By substitution,
k = 0.030 M / 0.020 M x (0.072 M)²
k = 289.35 M⁻²
