43 Which temperature change indicates an increase in the average kinetic energy of the molecules in a sample?(1) 15°C to 298 K (
aleksandrvk [35]
The increase in the average kinetic energy of the molecules needs the increase of temperature. The relation of ℃ and K is n ℃ = m K -273. So if we change all the K unit to ℃ unit, we can get the answer is (1).

In an exactly.200M solution of benzoic acid, a monoprotic acid, the [H+] = 3.55 × 10–3M. What is the Ka for benzoic acid? 8.88 ×
kondaur [170]
Answer : Option C) 6.3 X 10^{-5}.

Explanation : Given is the concentration of benzoic acid is 0.200 M, now only one monoprotic acid ion is getting separated from it [[ H^{+} ].

So, the reaction will be as,

H C_{7} H_{6}O_{2}   ⇔  [ H^{+} ] + C_{7} H_{6}O_{2} .

We can use the ICE method for calculation,
 The molar concentration of H C_{7} H_{6}O_{2} is 0.200 M and the  [[ H^{+} ] is 3.55 X 10^{-5}.

So here on reactant side we get, (0.2 - 3.55 X 10^{-5}) = 0.196
 on the product it remains as 3.55 X 10^{-5}.

So, K_{a} = (3.55 X 10^{-5}) X (3.55 X 10^{-5}) / 0.196

We will get K_{a} as 6.42 X  10^{-5} which is close to 6.3 X 10^{-5}.
