🚀 Jumpstart: Ever wished to speed up things? From Wi-Fi to your fav song downloads? Well, chemists feel the same, and they have a secret tool - catalysts!

<ul>
	<li>A substance that says, &quot;Hey! Let&#39;s make this reaction faster!&quot; without being consumed.</li>
	<li>Not a magic trick, just good ol&#39; science.</li>
	<li>Imagine it&#39;s like the friend who sets up two of your other friends on a date. They make things happen but remain single at the end!</li>
</ul>

<ul>
	<li>Intermediate: This is like a pencil standing upright on its flat end. A bit unstable, but hangs in there for a while.</li>
	<li>Transition State: Like a pencil on its sharpened tip. Super unstable! Falls immediately.</li>
</ul>

💡 The catalyst forms an intermediate. The intermediate changes and boom💥, you have your reaction product. And guess what? The catalyst walks away unchanged, ready for more action!

<ul>
	<li>Offers an alt route (like a cool shortcut) for a reaction.</li>
	<li>Reduces activation energy (the energy to start a reaction). Less energy, more speed!</li>
	<li>A reaction&#39;s heat energy change remains the same with or without it.</li>
</ul>

<ul>
	<li>Temperature: Turns up the average energy but leaves activation energy alone.</li>
	<li>Catalyst: Keeps the average energy as is, but reduces activation energy.</li>
	<li>Both lead to more reaction success parties 🎉!</li>
</ul>

Let&rsquo;s Dive Deep: 2SO2(g) + O2(g) becomes 2SO3(g) super fast in the presence of NO2. Why?

<ul>
	<li>SO2 and NO2 mix to make SO3 and NO.</li>
	<li>Then, NO and a bit of O2 go back to make NO2.</li>
</ul>

a. NO2 speeds things up and is both used and reformed in the process. It&rsquo;s like a bungee jump; goes in and bounces back! b. Energy profile doodles would show the energy of our reactants, intermediates, and products. The catalyzed reaction would need less energy bumps.

Life&#39;s Own Catalysts: Enzymes

<ul>
	<li>Enzymes: Nature&#39;s special catalysts.</li>
	<li>Without them, we&#39;d be waiting millions of years for stuff.</li>
	<li>They&#39;re super picky! One enzyme for one job. Efficient, right?</li>
</ul>

Catalysts are eco-warriors. They cut down energy use and waste. They&rsquo;ve even made painkillers like ibuprofen easier to make. They&#39;re so cool, they&#39;ve won Nobel Prizes!

Research on a catalyst. Maybe

<ul>
	<li>Iron in ammonia production</li>
	<li>Lactase helping you enjoy ice cream without tummy troubles. Then, tell your non-scientist friend about it in 5 mins.</li>
</ul>

<ul>
	<li>How does a catalyst affect both forward and backward reactions?</li>
	<li>What&#39;s so cool about transition elements as catalysts?</li>
</ul>
