Consider the following mechanism for a reaction: 2 NO (g) ⇌ N2O2 (g) fast

N2O2 (g) + H2 (g) --> N2O (g) + H2O (g) slow

N2O (g) + H2 (g) --> N2 (g) + H2O (g) fast

What is the predicted rate law?

What state of matter is ice a. liquid b. element c. solid d. gas

Which statement is true about a catalyst? a: a catalyst decreases the rate of the reaction. b. a catalyst is consumed during a chemical reaction. c. a catalyst lowers the activation energy of a reaction. d. a catalyst increases the reactant concentration during a reaction.

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.)
