**ABSTRACT**

An exact analysis of
rotation effects on unsteady flow of an incompressible fluid past a uniformly
accelerated infinite vertical plate with variable temperature and mass
diffusion, in the presence of chemical reaction of first order. The plate temperature is raised linearly with
time and the concentration level near the plate is also raised to The dimensionless governing equations are solved using Laplace-transformtechnique. The velocity profiles, temperature and concentration are studied for
different physical parameters like chemical reaction parameter, thermal Grashof
number, mass Grashof number, Schmidt number, Prandtl number and time. It is
observed that the velocity increases with increasing values of thermal Grashof
number or mass Grashof number. It is also observed that the velocity increases
with decreasing magnetic field parameter or rotation parameter Ω.**
