What is the NEET Daily High-Yield 10-MCQ Challenge?

The NEET Daily Challenge is a curated 10-minute speed drill featuring 10 authentic NCERT questions (3 Physics, 3 Chemistry, and 4 Biology) from crucial high-yield topics. It resets every midnight with a fresh set of questions and tracks your consecutive day study streak.

How does the Daily Streak system work?

Each time you complete today's challenge, your streak increases by 1 day. Completing challenges consecutive days builds your streak and unlocks milestone badges (Bronze, Silver, Gold, and Diamond AIIMS Aspirant). If you miss a day, the streak resets.

Are step-by-step solutions provided for all questions?

Yes. Immediately upon submitting your challenge, you receive an instant diagnostic scorecard along with detailed, bilingual (English & Hindi) step-by-step explanations for all 10 questions.

What is the marking scheme for the Daily Challenge?

The daily challenge follows the official NTA NEET UG pattern: +4 marks for each correct answer and -1 mark for each incorrect answer, for a total of 40 marks in 10 minutes.

Question 6 of 10 · +4 / -1

Why does a small rise in temperature (e.g., a 10 °C increase from 298 K to 308 K) cause a dramatic doubling or tripling of the reaction rate, even though the average molecular kinetic energy increases by only ~3%?

तापमान में मामूली वृद्धि (जैसे 298 K से 308 K तक 10 °C की वृद्धि) अभिक्रिया की दर को लगभग दोगुना या तीन गुना क्यों कर देती है, जबकि अणुओं की औसत गतिज ऊर्जा केवल ~3% ही बढ़ती है?

A

Because the collision frequency Z increases by 200%क्योंकि टक्कर आवृत्ति Z में 200% की वृद्धि होती है क्योंकि टक्कर आवृत्ति Z में 200% की वृद्धि होती है

B

Because the activation energy Ea drops by 50% for every 10 °C riseक्योंकि प्रत्येक 10 °C वृद्धि पर सक्रियण ऊर्जा Ea में 50% की कमी आती है क्योंकि प्रत्येक 10 °C वृद्धि पर सक्रियण ऊर्जा Ea में 50% की कमी आती है

C

Because according to the Maxwell-Boltzmann distribution, the fraction of molecules possessing kinetic energy greater than or equal to the activation energy (E ≥ Ea) nearly doublesक्योंकि मैक्सवेल-बोल्ट्जमान वितरण के अनुसार, सक्रियण ऊर्जा के बराबर या उससे अधिक गतिज ऊर्जा (E ≥ Ea) रखने वाले अणुओं का अंश लगभग दोगुना हो जाता है क्योंकि मैक्सवेल-बोल्ट्जमान वितरण के अनुसार, सक्रियण ऊर्जा के बराबर या उससे अधिक गतिज ऊर्जा (E ≥ Ea) रखने वाले अणुओं का अंश लगभग दोगुना हो जाता है

D

Because the volume of the reaction vessel expands by a factor of 2क्योंकि अभिक्रिया पात्र का आयतन 2 गुना बढ़ जाता है क्योंकि अभिक्रिया पात्र का आयतन 2 गुना बढ़ जाता है
