When multiplying by a constant, raise Kp to the power of that constant.
When the reaction is reversed, it gives the inverse of Kp.
Kp^(-1/2) = (7.8 x 10^-16)^(-1/2) = 3.6 x 10^7
The balanced reaction that describes the reaction between sulfuric and sodium hydroxide to produce sodium sulfate and water is expressed <span>H2SO4 + 2NaOH → 2H2O + Na2SO4. When 65.5 grams of sodium hydroxide reacts with excess sulfur, we need first to convert the mass to moles and multiply by stoich ratio 2/2 or 1. Hence the moles is multiplied to the molar mass of water. The final answer is 29.475 grams water.</span>
The time needed by the bike to reach the final velocity is 3 .75 seconds ,Option C is the write answer.
<h3>What is Velocity ?</h3>
It is defined as the distance covered by an object in a given amount of time. It is a vector quantity , its unit is m/s , km/hr etc.
It is given in the question that
Initial Velocity = 20m/s
Final Velocity = 35m/s
Acceleration = 4m/sq.s
Time = ?
The equation of motion
v = u +at will be used
35 = 20 + 4 * t
15 = 4* t
t = 3.75 seconds
Therefore the time needed by the bike to reach the final velocity is 3 .75 seconds.
