Physics
A bicyclist starts from rest and accelerates at 4 m/s^2 for 3 seconds. The cyclist then travels for 20s at a constant speed. How far does the cyclist travel? I got 138 m but I'm not sure if I'm right?

1. Statement-I : Fractional order reactions are not elementary reactions. Statement-II : For an elementary reaction, order must be same as molecularity. are these statements true? give reason.

chemistry kinetics
Statement-I : For an endothermic reaction, the activation energy is less than the change in enthalpy. Statement-II: Activation energy of a reaction, at a given temperature can never be greater than its change in enthalpy are these statements true? give reason

chemistry kinetics
The reaction SO2Cl2(g) → SO2(g) + Cl2(g) is a first order reaction carried out at constant volume at 600 K whose t1/2 is 4.1 hr. The initial pressure of SO2Cl2 is 1.25 atm. What will be the total pressure of the system after 1 hour?

chemistry kinetics
Decomposition of an organic compound A follows first order kinetics. Initial concentration of A is 2 M. If rate constant of the decomposition is 3.58 × 10^−6 min^-1 , calculate the rate after 3 hours.
