For chemical reactions involving ideal gases, the equilibrium constant k can be expressed either in terms of the concentrations of the gases (in m) or as a function of the partial pressures of the gases (in atmospheres). in the latter case, the equilibrium constant is denoted as kp to distinguish it from the concentration-based equilibrium constant kc (sometimes referenced as just k).for the reaction 2ch4(g)⇌c2h2(g)+3h2(g) kc = 0.140 at 1778 ∘c . what is kp for the reaction at this temperature? express your answer numerically.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
