At a certain temperature this reaction follows first-order kinetics with a rate constant of 0.0667 s¯¹: NH,OH (aq) → NH, (aq)+H,O (aq) Suppose a vessel contains NH4OH at a concentration of 0.360M. Calculate the concentration of NH4OH in the vessel 15.0 seconds later. You may assume no other reaction is important. Round your answer to 2 significant digits. M x10 X ?

A substance undergoes first-order decomposition. After 42 min at 500°C, only 12.5% of the original sample remains. What is the half-life of the decomposition?   Round your answer to 2 decimal places.

A chemical reaction (starting from pure starting material A) A → Products has expired in 30 minutes to exactly 30%. After which time is 80% conversion achieved, if the reaction obeys a velocity law a) zeroth b) first order?

The rate at which a certain drug is eliminated by the body follows first-order kinetics, with a half life of  69 minutes.Suppose in a particular patient the concentration of this drug in the bloodstream immediately after injection 1.9 is . What will the concentration be  207 minutes later? Round your answer to  2 significant digits.

Consider the reaction 2AB(g) → A2(g) + B2(g). If [AB] at 96 minutes was 0.71OM and dropped to 0.520M by 320.minutes, calculate the rate of consumption during this time frame.

In the nuclear industry, workers use a rule of thumb that the radioactivity from any sample will be harmless after 10 half-lives. What fraction of a radioactive sample remains after this time? (Radioactive decay obeys first-order kinetics.)

At a certain temperature this reaction follows second-order kinetics with a rate constant of 64.6M¹s¹: NH,OH(aq) → NH, (aq)+H,O(aq) Suppose a vessel contains NH OH at a concentration of 0.170M.
