রাসায়নিক সাম্যাবস্থা হল একটি ভারসাম্যপূর্ণ অবস্থা যেখানে সম্মুখ ও বিপরীত বিক্রিয়ার হার সমান হয়। এই ভারসাম্যটি স্থায়ী হয়, তবে বিক্রিয়াটি সম্পূর্ণ হয় না। উভয় দিক থেকেই বিক্রিয়া চলতে থাকে, তবে সাম্যাবস্থার অবস্থায় বিক্রিয়ার হার সমান থাকে।
সাম্যাবস্থার স্থায়িত
সাম্যাবস্থা একটি স্থিতিশীল অবস্থা। এটি একটি নির্দিষ্ট তাপমাত্রায় স্থায়ী থাকে। তবে, তাপমাত্রা পরিবর্তন করলে সাম্যাবস্থার অবস্থান পরিবর্তিত হতে পারে।
বিক্রিয়ার অসম্পূর্ণতা
রাসায়নিক সাম্যাবস্থায়, বিক্রিয়ার বিক্রিয়ক এবং উৎপাদনের পরিমাণ সমান হয় না। বিক্রিয়া সম্পূর্ণ না হওয়ার কারণ হল সম্মুখ ও বিপরীত বিক্রিয়ার হার সমান হয়।
উভয় দিক থেকে সাম্যাবস্থার প্রতিষ্ঠা
রাসায়নিক সাম্যাবস্থায়, বিক্রিয়া উভয় দিক থেকেই ঘটে। সম্মুখ বিক্রিয়ায় বিক্রিয়কগুলি উৎপাদে পরিণত হয়। বিপরীত বিক্রিয়ায় উৎপাদগুলি বিক্রিয়কে পরিণত হয়।
