Answer:

r=-0.033\frac{M}{s}

Explanation:

Hello!

In this case, since the average rate of reaction is computed as a change given by:

r=\frac{\Delta [NH_4NO_2 ]}{\Delta t}

In such a way, given the concentrations at the specified times, we plug them in to obtain:

r=\frac{(1.48M-4.12M)}{(330s-250s)}\\\\r=-0.033\frac{M}{s}

Whose negative sign means the concentration decreased due to the decomposition.

Best regards!

What happen when chlorine gas is passed into concentrated solution of naoh​
mars1129 [50]

Answer: By Stoichiometry, 3 moles of chlorine gas reacts with 6 moles of sodium hydroxide solution to form 5 moles of sodium chloride, 1 mole of sodium chlorate (V) and 3 moles of water. Hence, the reaction between chlorine gas and hot, concentrated NaOH solution yields Sodium chloride and sodium chlorate(V).

Explanation: Hope it helps :)
