Card 1रासायनिक गतिकी का परिचय

रासायनिक गतिकी क्या है?

Answer

रासायनिक गतिकी रसायन विज्ञान की वह शाखा है जो अभिक्रिया दरों और उनकी क्रियाविधियों के अध्ययन से संबंधित है। यह बताती है कि कोई अभिक्रिया कितनी तेज़ होती है और उसकी गति को क्या नियंत्रित करता है।

Card 2Introduction to chemical kinetics

What is chemical kinetics?

Answer

Chemical kinetics is the branch of chemistry that deals with the study of reaction rates and their mechanisms. It explains how fast a reaction occurs and what controls its speed.

Card 3Introduction to chemical kinetics

What is the difference between thermodynamics and chemical kinetics?

Answer

Thermodynamics tells only about the feasibility of a reaction, while chemical kinetics tells about the rate of a reaction. A reaction may be feasible but still very slow.

Card 4रासायनिक गतिकी का परिचय

ऊष्मागतिकी और रासायनिक गतिकी में क्या अंतर है?

Answer

ऊष्मागतिकी केवल किसी अभिक्रिया की संभाव्यता के बारे में बताती है, जबकि रासायनिक गतिकी अभिक्रिया की दर के बारे में बताती है। कोई अभिक्रिया संभव हो सकती है, लेकिन फिर भी बहुत धीमी हो सकती है।

Card 5अभिक्रिया की दर

अभिक्रिया की दर क्या है?

Answer

अभिक्रिया की दर किसी अभिकारक या उत्पाद की सांद्रता में प्रति इकाई समय होने वाला परिवर्तन है। किसी अभिकारक के लिए: R के लुप्त होने की दर = -Δ[R]/Δt. किसी उत्पाद के लिए: P के प्रकट होने की दर = +Δ[P]/Δt

Card 6Rate of reaction

What is the rate of a reaction?

Answer

Rate of a reaction is the change in concentration of a reactant or product per unit time. For a reactant: Rate of disappearance of R = -Δ[R]/Δt. For a product: Rate of appearance of P = +Δ[P]/Δt.

Card 7Rate of reaction

How is instantaneous rate written?

Answer

Instantaneous rate is the rate at a particular moment of time. r_inst = -d[R]/dt = d[P]/dt. It is obtained from the slope of the tangent to the concentration-time curve.

Card 8अभिक्रिया की दर

तात्कालिक दर कैसे लिखी जाती है?

Answer

तात्कालिक दर समय के किसी विशेष क्षण पर होने वाली दर है। r_inst = -d[R]/dt = d[P]/dt. इसे सांद्रता-समय वक्र पर खींची गई स्पर्शरेखा की ढलान से प्राप्त किया जाता है।
