本文从理论上研究了在二阶动量滑移模型下Arrhenius活化能和二元化学反应组分的集体效应，这是迄今为止尚未研究过的。为了支持这些声明，此外，导电边界层流动和热传输已被认为是一个指数拉伸片。本文研究了活化能、温差比参数、一阶和二阶滑移参数、化学反应速率对流体速度、流体温度和化学物种浓度的影响，并通过图解的方式进行了详细的讨论。通过适当的变换将偏微分方程转化为非线性高耦合常微分方程组，然后采用三步Lobatto伊利亚格式的有限差分配置法进行数值求解。所得到的结果证实，一个很好的协议是实现与那些可用的公开文献。结果表明，化学反应速率和温差比参数的存在使浓度分布减小，而活化能的变化则相反。
This paper is communicated theoretically to study the collective effects of Arrhenius activation energy and binary chemically reactive species in the presence of the second order momentum slip model which has not been studied so far. To support these declaration in addition with electrically conducting boundary layer flow and heat transport have considered towards an exponential stretching sheet. The current study incorporates the impact of activation energy, temperature difference ratio parameter, 1st and 2nd order slip parameter, chemical reaction rate on fluid velocity, fluid temperature and concentration of chemical species are elaborated through graphically and discussed in detail. Appropriate transformations are betrothed to acquire nonlinear highly coupled ordinary differential equations (ODE'S) from partial differential equations which are then solved numerically by employing finite difference collocation process that apply three-stage Lobatto Ilia scheme. The obtained results confirm that an excellent agreement is achieved with those available in open literature. It is found that concentration profile decreases in the presence of chemical reaction rate and temperature difference ratio parameter whereas opposite demeanour is seen for activation energy.
