Class 11th

The equation can be written as-

A^p+_x  +  B^q- _y ? xA^p+ (aq) +  yB^q-

S moles of A and B dissolves to give x S moles of A^p+ and y S moles of Bq-.

K_sp = [A^p+]^x   [B^q-]^y = [x5]^x [y5]^y

= x^x y ^y 5 ^x+y

The ratio of the Class 11 and Class 12 questions from Biology asked in the NEET 2025 exam is given in the table below. 

Some of the topics with a high weightage in the NEET question paper are given below, along with the number of questions asked. 

Note: The NEET Biology chapter-wise topics mentioned above are based on this year, and the weigtages may change next year. 

In general, the difficulty level of the NEET Biology section is easy to moderate. As compared to the other two sections, Biology has the lowest difficulty level. Moreover, the majority of the candidates score the highest in this section. According to the NEET 2025 analysis by the students and experts, even though the difficulty level of Biology was the easiest, some of the questions were lengthy and tricky in nature, making it more time consuming to answer or solve. 

Linear motion is one-dimensional motion. It refers to motion in a single direction or in a straight line. In linear motion, the object either moves forward or backward along one axis, i.e. x-axis. For example - a ball dropped from a height vertically downward or a car moving straight on a road. Motion in a Plane refers to an object moving in two dimensions, usually along x and y axes. For example, a football kicked at an angle.
